Chemosensors of Ion and Molecule Recognition particular, we obtain a sufficient condition on the kernel of an integral operator or the symbol of a pseudodifferential operator which implies that the operator is trace-class. This result significantly improves a sufficient condition due to Daubechies and Hörmander.

In this chapter we review some methods for approximation of the inverse frame operator associated to general frames and develop more specific methods for Gabor frames.

The first class consists of all integrable, non-negative windows. that are supported by and strictly de

Although such operators have been in use implicitly for quite some time, this paper appears to be the first systematic mathematical treatment of Gabor multipliers. Indeed,

We present some connections between these algebras and Gabor frames, and use them to derive some well-known results and their generalizations such as the density property in Gabor analysis, as well as some new ones such as a characterization of the Gabor frames (for subspaces) admitting un
