Symbolic calculus for a class of pseudodifferential operators with applications to compactness
Ãrpád Bényi, Tadahiro Oh, Rodolfo H. Torres
We prove a symbolic calculus for a class of pseudodifferential operators, and discuss its applications to -compactness via a compact version of the theorem.

Compact theorem à la Stein
Ãrpád Bényi, Guopeng Li, Tadahiro Oh +1
We prove a compact theorem, involving quantitative estimates, analogous to the quantitative classical theorem due to Stein. We also discuss the -to-…

Compact bilinear operators and paraproducts revisited
Ãrpád Bényi, Guopeng Li, Tadahiro Oh +1
We present a new proof of the compactness of bilinear paraproducts with CMO symbols. By drawing an analogy to compact linear operators, we first explore further properties of compa…
