Certain invariants of generic matrix algebras
Abstract
Let K be a field of characteristic zero, W be the associative unital algebra generated by two generic traceless matrices X, Y. We also handle the Lie subalgebra L of the algebra W consisting of its Lie elements. Consider the subgroup G=⟨e21−e12⟩ of the special linear group SL2(K) of order 4. In this study, we give free generators of the algebras WG and LG of invariants of the group G as a C(W)G-module.
