Abstract :
We are in progress of extending the family of ‘q-deformed operators’ considered in the previous papers by
joining to them q-subnormal as well as q-formally subnormal ones. It turns out that q-positive definiteness,
a notion generalizing Halmos’ standard positive definiteness of bounded subnormal operators, is likewise
central for our new scheme.
