Download or read book Gradient Flows written by Luigi Ambrosio and published by Springer Science & Business Media. This book was released on 2008-10-29 with total page 333 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book is devoted to the theory of gradient flows in the general framework of metric spaces, and in the more specific setting of the space of probability measures, which provide a surprising link between optimal transportation theory and many evolutionary PDE's related to (non)linear diffusion. Particular emphasis is given to the convergence of the implicit time discretization method and to the error estimates for this discretization, extending the well established theory in Hilbert spaces. The book is split in two main parts that can be read independently of each other.

Download or read book Words and functions communicating in english written by Elena Ungari and published by EDUCatt - Ente per il diritto allo studio universitario dell'Università Cattolica. This book was released on 2015-02-04 with total page 319 pages. Available in PDF, EPUB and Kindle. Book excerpt: Il presente lavoro intende essere un supporto per lo studio e l’esercitazione della Lingua Inglese soprattutto nelle sue particolarità lessicali e funzionali-comunicative. Lo strumento didattico qui proposto si propone innanzitutto di aiutare gli studenti ad ampliare il proprio vocabolario e ad esercitarlo correttamente in contesti scritti, quindi di fornire agli studenti stessi gli strumenti linguistici adeguati per l’approccio al testo scritto ed alla sua comprensione. Il volume si compone di nove Unità, organizzate tematicamente. Alcune di queste sono a loro volta suddivise in due parti, ognuna delle quali basata su argomenti fra loro affini o correlati. Le aree tematiche scelte sono fra quelle più familiari allo studente e riscontrabili nelle situazioni ed esperienze della quotidianità: relazioni interpersonali, familiari e sociali, le attività di ogni giorno, la scuola, lo sport, gli hobbies ed il tempo libero, il cibo, lo shopping, l’ambiente, i viaggi ed il turismo. Ogni Unità si articola in diverse sezioni, di difficoltà crescente, che intendono guidare lo studente nella progressiva acquisizione della padronanza della lingua nel suo passaggio dall’organizzazione frasale a quella testuale. All’interno di ogni singola Unità, la prima sezione è denominata “Vocabulary”: si tratta di un elenco di vocaboli e funzioni comunicative fondamentali, relativi al tema oggetto dell’Unità; tali vocaboli e funzioni sono presentati nella versione inglese e nella traduzione italiana. A completamento viene fornita la spiegazione di parole, locuzioni o aspetti lessicali e comunicativi, che possono essere di interesse particolare per gli studenti o che per gli stessi possono essere motivo di confusione La seconda sezione è denominata “Testing Vocabulary” e comprende esercizi che testano la capacità di usare correttamente all’interno di semplici frasi il vocabolario acquisito. La terza sezione prende in esame il meccanismo di formazione delle parole (Word Formation) attraverso l’ utilizzo di suffissi o prefissi. Tale sezione si correda di esercizi che richiedono allo studente il completamento di spazi bianchi (gaps) con parole create da un vocabolo-base fornito. La quarta sezione si concentra sulla comprensione testuale (Reading Comprehension). Dopo l’acquisizione del lessico di base, gli studenti possono così avvicinarsi al testo nella sua più articolata e complessa organizzazione. Gli esercizi scelti a tale riguardo comprendono testi con spazi bianchi da riempirsi con vocaboli forniti a scelta multipla (multiple choice cloze texts) e / o testi completi corredati da domande con opzioni di risposte sempre a scelta multipla. Alcune Unità contemplano in tale sezione esercizi che richiedono di trovare informazioni in un testo e di completare una griglia relativa con dati desunti dal brano proposto. In altri capitoli, invece, si trovano jumbled texts, brevi frasi da riorganizzare in modo tale da ottenere un brano coeso. Ogni Unità comprende inoltre una Grammar Revision. Lontano dal volere essere una sezione grammaticale esaustiva, tale parte intende essere un “richiamo” degli argomenti grammaticali prevalenti all’interno dell’Unità e, soprattutto, un invito alla revisione delle particolarità grammaticali stesse all’interno del testo di grammatica di riferimento adottato. Al termine di questa introduzione si precisa che le fonti bibliografiche da cui sono stati tratti brani e / o esercizi contenuti all’interno della seguente dispensa sono chiaramente indicate. Tale materiale, desunto da testi che spaziano dalla preparazione al PET a manuali adatti alla prepazione per il superamento del CAE, sono stati sottoposti ad una rielaborazione per conformarli alle esigenze dei destinatari della seguente pubblicazione. Come grammatica di riferimento si è preferito avvalersi del testo: Michael Swan, Practical English Usage, Oxford. Nato dall’esperienza didattica maturata in questi ultimi anni nell’ambito del SELDA e dal riscontro delle difficoltà che gli studenti si trovano ad affrontare nel loro approccio alla Lingua Inglese, il volume si propone ora auspicabilmente come ulteriore e valido strumento di studio e di approfondimento.

Available in PDF, EPUB and Kindle. Book excerpt: This textbook introduces geometric measure theory through the notion of currents. Currents, continuous linear functionals on spaces of differential forms, are a natural language in which to formulate types of extremal problems arising in geometry, and can be used to study generalized versions of the Plateau problem and related questions in geometric analysis. Motivating key ideas with examples and figures, this book is a comprehensive introduction ideal for both self-study and for use in the classroom. The exposition demands minimal background, is self-contained and accessible, and thus is ideal for both graduate students and researchers.

Download or read book Geometry and Complexity Theory written by J. M. Landsberg and published by Cambridge University Press. This book was released on 2017-09-28 with total page 353 pages. Available in PDF, EPUB and Kindle. Book excerpt: Two central problems in computer science are P vs NP and the complexity of matrix multiplication. The first is also a leading candidate for the greatest unsolved problem in mathematics. The second is of enormous practical and theoretical importance. Algebraic geometry and representation theory provide fertile ground for advancing work on these problems and others in complexity. This introduction to algebraic complexity theory for graduate students and researchers in computer science and mathematics features concrete examples that demonstrate the application of geometric techniques to real world problems. Written by a noted expert in the field, it offers numerous open questions to motivate future research. Complexity theory has rejuvenated classical geometric questions and brought different areas of mathematics together in new ways. This book will show the beautiful, interesting, and important questions that have arisen as a result.

Available in PDF, EPUB and Kindle. Book excerpt: Approximately fifty articles that were published in The Mathematical Intelligencer during its first eighteen years. The selection demonstrates the wide variety of attractive articles that have appeared over the years, ranging from general interest articles of a historical nature to lucid expositions of important current discoveries. Each article is introduced by the editors. "...The Mathematical Intelligencer publishes stylish, well-illustrated articles, rich in ideas and usually short on proofs. ...Many, but not all articles fall within the reach of the advanced undergraduate mathematics major. ... This book makes a nice addition to any undergraduate mathematics collection that does not already sport back issues of The Mathematical Intelligencer." D.V. Feldman, University of New Hamphire, CHOICE Reviews, June 2001.

Download or read book Sets of Finite Perimeter and Geometric Variational Problems written by Francesco Maggi and published by Cambridge University Press. This book was released on 2012-08-09 with total page 475 pages. Available in PDF, EPUB and Kindle. Book excerpt: The marriage of analytic power to geometric intuition drives many of today's mathematical advances, yet books that build the connection from an elementary level remain scarce. This engaging introduction to geometric measure theory bridges analysis and geometry, taking readers from basic theory to some of the most celebrated results in modern analysis. The theory of sets of finite perimeter provides a simple and effective framework. Topics covered include existence, regularity, analysis of singularities, characterization and symmetry results for minimizers in geometric variational problems, starting from the basics about Hausdorff measures in Euclidean spaces and ending with complete proofs of the regularity of area-minimizing hypersurfaces up to singular sets of codimension 8. Explanatory pictures, detailed proofs, exercises and remarks providing heuristic motivation and summarizing difficult arguments make this graduate-level textbook suitable for self-study and also a useful reference for researchers. Readers require only undergraduate analysis and basic measure theory.

This book was released on 2013-12-08 with total page 419 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume addresses the key issue of the initial education and lifelong professional learning of teachers of mathematics to enable them to realize the affordances of educational technology for mathematics. With invited contributions from leading scholars in the field, this volume contains a blend of research articles and descriptive texts. In the opening chapter John Mason invites the reader to engage in a number of mathematics tasks that highlight important features of technology-mediated mathematical activity. This is followed by three main sections: An overview of current practices in teachers’ use of digital technologies in the classroom and explorations of the possibilities for developing more effective practices drawing on a range of research perspectives (including grounded theory, enactivism and Valsiner’s zone theory). A set of chapters that share many common constructs (such as instrumental orchestration, instrumental distance and double instrumental genesis) and research settings that have emerged from the French research community, but have also been taken up by other colleagues. Meta-level considerations of research in the domain by contrasting different approaches and proposing connecting or uniting elements
