Matrix units in the simple components of rational group algebras
Gurmeet Kaur Bakshi, Jyoti Garg
For the rational group algebra of a finite group , we provide an effective method to compute a complete set of matrix units and, in particular, primitive orthogona…

Rational group algebras of generalized strongly monomial groups: primitive idempotents and units
Gurmeet K. Bakshi, Jyoti Garg, Gabriela Olteanu
We present a method to explicitly compute a complete set of orthogonal primitive idempotents in a simple component with Schur index 1 of a rational group algebra for…
