Abstract

We prove First Fundamental Theorems of Coinvariant Theory for the standard coactions of the quantum groups Oq(GLt(K)) and Oq(SLt(K)) on the quantized algebra Oq(Mm,t(K)) ⊗ Oq(Mt, n(K)). (Here K is an arbitrary field and q an arbitrary nonzero scalar.) In both cases, the set of co-invariants is a subalgebra of Oq(Mm,t(K)) ⊗ Oq(Mt, n(K)), which we identify.
