Abstract: Using properties of an integral transform giving directly the matrix elements of a quantum mechanical operator from the corresponding classical function, we restrict the class of distributions corresponding to bounded operators. As a consequence, we can exhibit a class of functions yielding traceclass operators, and give a bound on their tracenorm. © 1980 SpringerVerlag.
