Problems of classifying associative or Lie algebras and triples of symmetric or skew-symmetric matrices are wild
Genrich Belitskii, Ruvim Lipyanski, Vladimir V. Sergeichuk
We prove that the problems of classifying triples of symmetric or skew-symmetric matrices up to congruence, local commutative associative algebras with zero cube radical and square…
The problems of classifying pairs of forms and local algebras with zero cube radical are wild
Genrich Belitskii, Vitalij M. Bondarenko, Ruvim Lipyanski +2
We prove that over an algebraically closed field of characteristic not two the problems of classifying pairs of sesquilinear forms in which the second is Hermitian, pairs of biline…
Automorphisms of Categories of Free Modules, Free Semimodules, and Free Lie Modules
Yefim Katsov, Ruvim Lipyanski, Boris Plotkin
In algebraic geometry over a variety of universal algebras , the group of automorphisms of the category of finitely generated free algebras of is of gre…
Automorphisms of categories of free modules and free Lie algebras
R. Lipyanski, B. Plotkin
We prove that the group of automorphisms of the category of free modules over Noterian rings is semi-inner and present also a short proof of a similar result for the variery of Lie…
