Download or read book Algebraic Theory of Quasivarieties written by Viktor A. Gorbunov and published by Springer Science & Business Media. This book was released on 1998-09-30 with total page 314 pages. Available in PDF, EPUB and Kindle. Book excerpt: The theory of quasivarieties constitutes an independent direction in algebra and mathematical logic and specializes in a fragment of first-order logic-the so-called universal Horn logic. This treatise uniformly presents the principal directions of the theory from an effective algebraic approach developed by the author himself. A revolutionary exposition, this influential text contains a number of results never before published in book form, featuring in-depth commentary for applications of quasivarieties to graphs, convex geometries, and formal languages. Key features include coverage of the Birkhoff-Mal'tsev problem on the structure of lattices of quasivarieties, helpful exercises, and an extensive list of references.
