Ebook: Finite Dimensional Algebras

This English edition has an additional chapter "Elements of Homological Al­ gebra". Homological methods appear to be effective in many problems in the theory of algebras; we hope their inclusion makes this book more complete and self-contained as a textbook. We have also taken this occasion to correct several inaccuracies and errors in the original Russian edition. We should like to express our gratitude to V. Dlab who has not only metic­ ulously translated the text, but has also contributed by writing an Appendix devoted to a new important class of algebras, viz. quasi-hereditary algebras. Finally, we are indebted to the publishers, Springer-Verlag, for enabling this book to reach such a wide audience in the world of mathematical community. Kiev, February 1993 Yu.A. Drozd V.V. Kirichenko Preface The theory of finite dimensional algebras is one of the oldest branches of modern algebra. Its origin is linked to the work of Hamilton who discovered the famous algebra of quaternions, and Cayley who developed matrix theory. Later finite dimensional algebras were studied by a large number of mathematicians including B. Peirce, C.S. Peirce, Clifford, ·Weierstrass, Dedekind, Jordan and Frobenius. At the end of the last century T. Molien and E. Cartan described the semisimple algebras over the complex and real fields and paved the first steps towards the study of non-semi simple algebras.

The theory of finite-dimensional algebras is one of the most fundamental domains of modern algebra, applied in several other parts of mathematics andin theoretical physics. This book, written by two of the leading researchersin the field and revised and augmented for the English edition, was translated from the Russian by a third leading specialist, who has contributed to it an appendix. The book presents both the basic classical theory and more recent results closely related to current research (some category theory including Morita's theorem, schemes of quivers andtensor algebras, duality, quasi-Frobenius, hereditary, serial algebras). Theonly prior knowledge assumed of the reader is linear algebra and, in places,a little group theory. Each chapter includes a series of exercises, illustrating the content and introducing more refined results: for the more complicated ones, hints for the solution are given - thus the book can be used as a textbook in class or for self-study, and as an up-to-date reference to the field.
