Abstract

In this work, we present some applications of the LpL^p-LqL^q boundedness of Fourier multipliers to PDEs on the noncommutative (or quantum) Euclidean space. More precisely, we establish LpL^p-LqL^q norm estimates for solutions of heat, wave, and Schr\"odinger type equations with Caputo fractional derivative in the case 1<p2q<.1 < p \leq 2 \leq q < \infty. Moreover, we obtain well-posedness of nonlinear heat and wave equations on the noncommutative Euclidean space.
