Witt equivalence of function fields of conics

Gladki, P.; Marshall, M. (Algebra and Discrete Mathematics, 2020)

Two fields are Witt equivalent if, roughly speaking, they have the same quadratic form theory. Formally, that is to say that their Witt rings of symmetric bilinear forms are isomorphic. This equivalence is well understood ...
Zero-sum subsets of decomposable sets in Abelian groups

Banakh, T.; Ravsky, A. (Algebra and Discrete Mathematics, 2020)

A subset D of an abelian group is decomposable if ∅ ≠ D ⊂ D + D. In the paper we give partial answers to an open problem asking whether every finite decomposable subset D of an abelian group contains a non-empty subset ...
