ABSTRACT
In this work we introduce and study a class of linear operators related to a finite measure space, for which its -Hilbert space is separable. These linear operators represent a generalization of pseudo-differential operators on
, where
is the unit circle with centre at the origin. We call these operators, S-operators or generalized pseudo-differential operators on S, where
is the corresponding finite measure space for which the
-space is separable. We give some
-boundedness and compactness results, and we also study the Hilbert–Schmidt property in connection with this class of linear operators. In the end we give some examples of finite measure spaces and corresponding S-operators for which we can apply our results.
