We study the classical problem of Kostant for Whittaker modules over Lie algebras and Lie
superalgebras. We give a sufficient condition for a positive answer to Kostant's problem for …

We give a complete combinatorial answer to Kostant's problem for simple highest weight
modules indexed by fully commutative permutations. We also propose a reformulation of …

This is a survey paper presenting the history and both old and new results related to
Kostant's problem. This problem asks for which modules over a semi-simple finite …
