Compactness for pseudo-differential and Toeplitz operators on modulation spaces

Elmira Nabizadeh-Morsalfard, Christine Pfeuffer, Nenad Teofanov +1

We deduce various norm equivalences, and convolution estimates for the modulation space $M_{(\omega )}^{♯,q}$ consisting of all $f\in M_{(\omega )}^{\infty ,q}$ such that $|V_ϕf \cdot ω|…
