Book excerpt: IN writing this tract, the chief difficulty has been to compress the material so as not to entirely outrun the prescribed limits of space.The theory is developed in an order which may seem unusual to readers already acquainted with other methods of treatment; but my object has been to obtain a fairly complete account in the minimum of space. If the methods of Weierstrass or Darboux had been adopted, a long and rather tedious discussion would have been needed for certain determinantal theorems (Arts. 24, 25), before the real problem of reduction could have been attacked. Further, the singular case would then have required an entirely separate discussion, of which the only satisfactory account is both involved and laborious.Both of these objections are avoided by the method used here, which is due in substance to Kronecker. And, in addition, the method lends itself to geometrical explanations (see Arts. 1, 13, 17 and Appendix) and is well adapted for the actual reduction of numerical examples, when once the roots of the fundamental determinant are known (see Arts. 2, 16, 19, 22). I hope that a frequent appeal to geometry may serve to make the algebra more easily understood.The omission of any account of Weierstrass's and Darboux's methods would be a serious blot, if the tract were intended to be exhaustive rather than suggestive; in particular Darboux's treatment of the case of unequal rootsl must always be regarded as a model of algebraical elegance. But accounts of these methods are already available to a certain extent (for references, see Art. 38); and consequently an exposition is less necessary here.I have devoted Chapter V to an exhibition of some applications of the theory; these may serve to convince the reader of its utility; and a glance at the table given in Art. 23 will shew that families containing more than four variables could not be exhaustively classified without the aid of invariant-factors. Indeed, even the case of four variables was not fully worked out (in spite of the assistance derived from space intuition) until Sylvester took the first step in the general theory by classifying the contacts of quadric surfaces (see Arts. 11, 18).In conclusion, my best thanks are due to the editors for giving me the opportunity of writing this tract; and to Mr. Leathem in particular for reading the manuscript and proofs. His care has enabled me to detect and remove many difficulties and ambiguities; but it is only too likely that others remain to be found after publication. The addition of the Appendix is due to Mr. Leathem's suggestion.The printing of the University Press stands in no need of praise from me; but I must thank the officials for their excellent reproductions of my drawings, and for their careful superintendence of the press-work in general.

Available in PDF, EPUB and Kindle. Book excerpt: AUTHOR'S PREFACE. This introduction to the classical theory of invariants of algebraic forms is divided into three parts of approximately equal length. Part I treats of linear transformations both from the standpoint of a change of the two points of reference or the triangle of reference used in the definition of the homogeneous coordinates of points in a line or plane, and also from the standpoint of projective geometry. Examples are given of invariants of forms f/ of low degrees in two or three variables, and the vanishing of an invariant of f is shown to give a geometrical property of the locus f = 0, which, on the one hand, is independent of the points of reference or triangle of reference, and, on the other hand, is unchanged by projection. Certain covariants such as Jacobians and Hessians are discussed and their algebraic and geometrical interpretations given; in particular, the use of the Hessian in the solution of a cubic equation and in the discussion of the points of inflexion of a plane cubic curve. In brief, beginning with ample illustrations from plane analytics, the reader is led by easy stages to the standpoint of linear transformations, their invariants and interpretations, employed in analytic projective geometry and modern algebra. Part II treats of the algebraic properties of invariants and covariants, chiefly of binary forms: homogeneity, weight, annihilators, semi-invariant leaders of covariants, law of reciprocity, fundamental systems, properties as functions of the roots, and production by means of differential operators. Any quartic equation is solved by reducing it to a canonical form by means of the Hessian (§ 33). Irrational invariants are illustrated by a carefully selected set of exercises (§ 35). Part III gives an introduction to the symbolic notation of Aronhold and Clebsch. The notation is first explained at length for a simple case; likewise the fundamental theorem on the types of symbolic factors of a term of a covariant of binary forms is first proved for a simple example by the method later used for the general theorem. In view of these and similar attentions to the needs of those making their first acquaintance with the symbolic notation, the difficulties usually encountered will, it is believed, be largely avoided. This notation must be mastered by those who would go deeply into the theory of invariants and its applications. Hilbert's theorem on the expression of the forms of a set linearly in terms of a finite number of forms of the set is proved and applied to establish the finiteness of a fundamental set of covariants of a system of binary forms. The theory of transvectants is developed as far as needed in the discussion of apolarity of binary forms and its application to rational curves (§§ 53-57), and in the determination by induction of a fundamental system of covariants of a binary form without the aid of the more technical supplementary concepts employed by Gordan. Finally, there is a discussion of the types of symbolic factors in any term of a concomitant of a system of forms in three or four variables, with remarks on fine and plane coordinates. For further developments reference is made at appropriate places to the texts in English by Salmon, Elliott, and Grace and Young, as well as to Gordan's Invariantentheorie. The standard work on the geometrical side of invariants is Clebsch-Lindemann, Vorlesungen über Geometrie. Reference may be made to books by W. F. Meyer, Apolaritdt und Rationale Curve, Bericht uber den gegenwarligen Stand der Invariantentheorie, and Formentheorie. Concerning invariant-factors, elementary divisors, and pairs of quadratic or bilinear forms, not treated here, see Muth, Elementartheiler, Bromwich, Quadratic Forms and their Classification by Means of Invariant Factors, and Bocher's Introduction to Higher Algebra....

Available in PDF, EPUB and Kindle. Book excerpt: The arithmetic theory of quadratic forms is a rich branch of number theory that has had important applications to several areas of pure mathematics--particularly group theory and topology--as well as to cryptography and coding theory. This book is a self-contained introduction to quadratic forms that is based on graduate courses the author has taught many times. It leads the reader from foundation material up to topics of current research interest--with special attention to the theory over the integers and over polynomial rings in one variable over a field--and requires only a basic background in linear and abstract algebra as a prerequisite. Whenever possible, concrete constructions are chosen over more abstract arguments. The book includes many exercises and explicit examples, and it is appropriate as a textbook for graduate courses or for independent study. To facilitate further study, a guide to the extensive literature on quadratic forms is provided.
