Semialgebras associated with nonunital algebras and $k$ -linear subcategories

Leonid Positselski

This paper is a sequel to arXiv:2307.13358 and arXiv:2308.16090. A construction associating a semialgebra with an algebra, subalgebra, and a coalgebra dual to the subalgebra played…

Tensor-Hom formalism for modules over nonunital rings

Leonid Positselski

We say that a ring $R$ is t-unital if the natural map $R \otimes_{R} R \to R$ is an isomorphism, and a left $R$ -module $P$ is c-unital if the natural map $P\rightarrow\operatorn…

Nonhomogeneous quadratic duality and curvature

Leonid Positselski

This is a slightly corrected version of the article published by Functional Analysis and its Applications in 1993. We define the quadratic duality for algebras with nonhomogeneous…
