We study the holomorphic twist of 3d $$\mathcal{N}=2$$ gauge theories in presence boundaries, and algebraic structure bulk boundary local operators. In twist, both operators form chiral algebras (a.k.a. vertex algebras). The algebra is commutative, endowed with a shifted Poisson bracket “higher” stress tensor; while module for bulk, may not be or have tensor. explicitly construct free Landau–Gi...

let $r$ be a commutative ring. in this paper we assert some properties of finitely generated comultiplication modules and fitting ideals of them.

we show that every semi-artinian module which is contained in a direct sum of finitely presented modules in $si[m]$, is weakly co-semisimple if and only if it is regular in $si[m]$. as a consequence, we observe that every semi-artinian ring is regular in the sense of von neumann if and only if its simple modules are $fp$-injective.
