We introduce the notion of essential support of a simple Gelfand-Tsetlin gln-module as an attempt to understand the character formula of such module. This support detects the weights having maximal possible Gelfand-Tsetlin ...

As in many other parts of the world, ‘academic literacy’ has emerged as both a concern and a contested concept in South African universities. In this article we focus specifically on academic reading, which we argue is a ...

The Drinfeld double D of the bosonization of a finite-dimensional Nichols algebra B(V) over a finite non-abelian group G is called a quantum group at a non-abelian group. We introduce Verma modules over such a quantum group ...
