Interpolations: a linear algebra approach
Andronick Arutyunov, Nikolay Korgin
This paper presents a unified linear-algebraic framework for interpolation problems, viewing different standart problems (Lagrange polynomials, Hermite splines, and trigonometric i…
Description of the structure of DG--algebras via characters on a groupoid
Andronick Arutyunov, Oleg Muravev
We construct a description of graded derivations in group algebras. Using this result for arbitrary graduation of the group algebra, we describe all possible structures of DG algeb…
Cohomology of n-categories and derivations in group algebras
Andronick Arutyunov, Alekseev Aleksandr
This work represents the concept of an n-groupoid and n-characters on n-groupoids as complex-valued maps from spaces of different classes of morphisms satisfying th…
Derivations of Group Algebras
A. A. Arutyunov, A. S. Mishchenko, A. I. Shtern
In the paper, a method of describing the outer derivations of the group algebra of a finitely presentable group is given. The description of derivations is given in terms of charac…
