โฆ Synopsis
In this paper we completely characterize the compact semi-commutator of two Toeplitz operators with bounded pluriharmonic symbols on the Bergman space of the polydisk. Several necessary and sufficient conditions are obtained for the commutator of two Toeplitz operators with bounded pluriharmonic symbols on the polydisk to be compact.

We consider the question for which square integrable analytic functions f and g on the unit disk the densely defined products T f T gร are bounded on the Bergman space.

In working with negations and t-norms, it is not uncommon to call upon the arithmetic of the real numbers even though that is not part of the structure of the unit interval as a bounded lattice.
