Algebraic theory of quasivarieties
В. А. Горбунов · OpenGrey (Institut de l'Information Scientifique et Technique) · 1998
The investigation is devoted to the construction of the algebraic theory on the quasi-varieties. The mosr attention is paid to the investigation of the grids of the quasi-varieties, finite-defined and subdirect-non-composed systems, independent axiomatization. The algebraic methods developed mainly by an author are used (method of superdirect and inverse limits, theory of quasi-Birkhoff classes, method of limit-projective systems, theory of decompositions in complete grids). Besides, the theoretical-grid methods are used widely. The results are used in the further investigations and lecturing of the special courses.
