On metacyclic p-group codes

Seema Chahal, Sugandha Maheshwary

In this article, we study the metacyclic p-group codes arising from finite semisimple group algebras. In [CM25], we studied group codes arising from metacyclic groups with order di…

Cut Groups: The Progress And The Problems

Seema Chahal, Sugandha Maheshwary

This article focuses on the study of cut groups, i.e., the groups which have only trivial central units in their integral group ring. We provide state of art for cut groups. The re…

Group rings and the RS-property

Gurmeet K. Bakshi, Sugandha Maheshwary, Inder Bir S. Passi

The object of this paper is to study (infinite) groups whose integral group rings have only trivial central units. This property is closely related to a property, here called the R…

Finite semisimple group algebra of a normally monomial group

Shalini Gupta, Sugandha Maheshwary

In this paper, the complete algebraic structure of finite semisimple group algebra of a normally monomial group is described. The main result is illustrated by computing the explic…

Extremely strong Shoda pairs with \texttt{GAP}

Gurmeet K. Bakshi, Sugandha Maheshwary

We provide algorithms to compute a complete irredundant set of extremely strong Shoda pairs of a finite group and the set of the primitive central idempotents of the rational g…
