Fourier multipliers and their applications to PDE on the quantum Euclidean space

Abstract

In this work, we present some applications of the $L^p$-$L^q$ boundedness of Fourier multipliers to PDEs on the noncommutative (or quantum) Euclidean space. More precisely, we establish $L^p$-$L^q$ norm estimates for solutions of heat, wave, and Schr\"odinger type equations with Caputo fractional derivative in the case $1 < p \leq 2 \leq q < \infty.$ Moreover, we obtain well-posedness of nonlinear heat and wave equations on the noncommutative Euclidean space.
