Multi-linear products with odd factors in pseudo-differential calculus with symbols in modulation spaces
arXiv:2110.12556
Abstract
We give sufficient conditions on the Lebesgue exponents for compositions of odd numbers of pseudo-differential operators with symbols in modulation spaces. As a byproduct, we obtain sufficient conditions for twisted convolutions of odd numbers of factors to be bounded on Wiener amalgam spaces.
