Finite groups, smooth invariants, and isolated quotient singularities
Amiram Braun
Let G < SL(V) be a finite group, V is finite dimensional over a field F, p=char F and S(V) is the symmetric algebra of V. We determine when the subring of G-invariants S(V)^G is a…

p-Groups and the Polynomial Ring of Invariants Question
Amiram Braun
Let G be a finite p-subgroup of GL(V), where p = char(F), and V is finite-dimensional over the field F. Let S(V) be the symmetric algebra of V, S(V)^G the subring of G-invariants,…
