Elliptic problems in Besov and Sobolev—Triebel—Lizorkin spaces of low regularity

Chepurukhina, I.S.; Murach, A.A. (Доповіді НАН України, 2021)

Elliptic problems with additional unknown distributions in boundary conditions are investigated in Besov and Sobolev–Triebel–Lizorkin spaces of low regularity, specifically of an arbitrary negative order. We find that ...
On the structure of some non-periodic groups whose subgroups of infinite special rank are transitively normal

Velychko, T.V. (Доповіді НАН України, 2021)

A group G has a finite special rank r, if every finitely generated subgroup of G can be generated by at most r elements, and there exists a finitely generated subgroup H which has exactly r generators. This paper is devoted ...
