The Twisted Derivation Problem for Group Rings

Dishari Chaudhuri

We study $(σ, τ)$ -derivations of a group ring $R G$ where $G$ is a group with center having finite index in $G$ and $R$ is a semiprime ring with $1$ such that either $R$ has no torsi…

A note on $(σ, τ)$ -Derivations on Commutative Algebras

Dishari Chaudhuri

We study universal mapping properties of $(σ, τ)$ -derivations over commutative algebras and characterize them over rings of integers of quadratic number fields. As a result we provi…

Skew-Symmetric Elements of Rational Group Algebras

Dishari Chaudhuri

Let $R G$ be the group ring of a finite group $G$ over a commutative ring $R$ with $1$ . An element $x$ in $R G$ is said to be skew-symmetric with respect to an involution $σ$ of $R G$ …

$(σ, τ)$ -Derivations of Group Rings

Dishari Chaudhuri

We study $(σ, τ)$ -derivations of a group ring $R G$ of a finite group $G$ over an integral domain $R$ with $1$ . As an application we extend a well known result on derivation of an in…
