Download or read book Rigidity and Symmetry written by Robert Connelly and published by Springer. This book was released on 2014-06-11 with total page 378 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book contains recent contributions to the fields of rigidity and symmetry with two primary focuses: to present the mathematically rigorous treatment of rigidity of structures and to explore the interaction of geometry, algebra and combinatorics. Contributions present recent trends and advances in discrete geometry, particularly in the theory of polytopes. The rapid development of abstract polytope theory has resulted in a rich theory featuring an attractive interplay of methods and tools from discrete geometry, group theory, classical geometry, hyperbolic geometry and topology. Overall, the book shows how researchers from diverse backgrounds explore connections among the various discrete structures with symmetry as the unifying theme. The volume will be a valuable source as an introduction to the ideas of both combinatorial and geometric rigidity theory and its applications, incorporating the surprising impact of symmetry. It will appeal to students at both the advanced undergraduate and graduate levels, as well as post docs, structural engineers and chemists.

Download or read book Discrete Geometry and Symmetry written by Marston D. E. Conder and published by Springer. This book was released on 2018-06-11 with total page 333 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book consists of contributions from experts, presenting a fruitful interplay between different approaches to discrete geometry. Most of the chapters were collected at the conference “Geometry and Symmetry” in Veszprém, Hungary from 29 June to 3 July 2015. The conference was dedicated to Károly Bezdek and Egon Schulte on the occasion of their 60th birthdays, acknowledging their highly regarded contributions in these fields. While the classical problems of discrete geometry have a strong connection to geometric analysis, coding theory, symmetry groups, and number theory, their connection to combinatorics and optimization has become of particular importance. The last decades have seen a revival of interest in discrete geometric structures and their symmetry. The rapid development of abstract polytope theory has resulted in a rich theory featuring an attractive interplay of methods and tools from discrete geometry, group theory and geometry, combinatorial group theory, and hyperbolic geometry and topology. This book contains papers on new developments in these areas, including convex and abstract polytopes and their recent generalizations, tiling and packing, zonotopes, isoperimetric inequalities, and on the geometric and combinatorial aspects of linear optimization. The book is a valuable resource for researchers, both junior and senior, in the field of discrete geometry, combinatorics, or discrete optimization. Graduate students find state-of-the-art surveys and an open problem collection.
Download or read book Handbook of Discrete and Computational Geometry written by Csaba D. Toth and published by CRC Press. This book was released on 2017-11-22 with total page 2354 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Handbook of Discrete and Computational Geometry is intended as a reference book fully accessible to nonspecialists as well as specialists, covering all major aspects of both fields. The book offers the most important results and methods in discrete and computational geometry to those who use them in their work, both in the academic world—as researchers in mathematics and computer science—and in the professional world—as practitioners in fields as diverse as operations research, molecular biology, and robotics. Discrete geometry has contributed significantly to the growth of discrete mathematics in recent years. This has been fueled partly by the advent of powerful computers and by the recent explosion of activity in the relatively young field of computational geometry. This synthesis between discrete and computational geometry lies at the heart of this Handbook. A growing list of application fields includes combinatorial optimization, computer-aided design, computer graphics, crystallography, data analysis, error-correcting codes, geographic information systems, motion planning, operations research, pattern recognition, robotics, solid modeling, and tomography.

Available in PDF, EPUB and Kindle. Book excerpt: "The original edition [...] inspired a whole generation of grateful workers in polytope theory. Without it, it is doubtful whether many of the subsequent advances in the subject would have been made. The many seeds it sowed have since grown into healthy trees, with vigorous branches and luxuriant foliage. It is good to see it in print once again." --Peter McMullen, University College London

Download or read book Flag Graphs and Symmetry Type Graphs written by María del Río Francos and published by . This book was released on 2014 with total page 141 pages. Available in PDF, EPUB and Kindle. Book excerpt: A map, as a 2-cell embedding of a graph on a closed surface, is called a $k$-orbit map if the group of automorphisms (or symmetries) of the map partitions its set of flags into $k$ orbits. In 2012, Steve Wilson introduced the concept of maniplex, aming to unify the notion of maps and abstract polytopes. In particular, maniplexes generalise maps on surfaces to higher ranks. The combinatorial structure of a maniplex of rank $(n-1)$ (or an $(n-1)$-maniplex) is completely determined by an edge-coloured $n$-valent graph with chromatic index $n$, with $n \ge 1$, often called the flag graph of the maniplex. Maps will be regarded as maniplexes of rank 2 (or 2-maniplexes), and defined as Lins and Vince studied the combinatorial maps since 1982-1983. Thus, similarly to maps, a $k$-orbit maniplex is one that has $k$ orbits of flags under the action of its automorphism group. In the first part of this thesis we introduce the notion of symmetry type graphs of maniplexes and make use of them to study $k$-orbit maniplexes, as well as fully-transitive 3-maniplexes. We classify all possible symmetry types of $k$-orbit 2-maniplexes for $k \le 5$, as well as all self-dual, properly and improperly, $k$-orbit maps with $k \le 7$. Moreover, we show that there are no fully-transitive $k$-orbit 3-maniplexes with $k > 1$ an odd number, we classify 3-orbit maniplexes and determine all face transitivities for 3- and 4-orbit maniplexes. Furthermore, we give generators of the automorphism group of a maniplex, given its symmetry typegraph. The second part of this work is motivated by the classification for $k$-orbit, up to $k \le 4$, that Orbanić, Pellicer and Weiss gave. Thus, motivated by their results, we use symmetry type graphs to extend such study and classify all the types of $k$-orbit maps with the same operations on maps, up to $k \le 6$. Furthermore, we studied other operations on maps, such as the chamfering and leapfrog operations. In particular, we determine all possible symmetry types of maps that result from other maps after applying the chamfering operation and give the number of possible flag-orbits that has the chamfering map of a $k$-orbit map.
