Abstract
This paper is a development of the results and techniques of the two papers (Carvalho-Neto and Planes in J Differ Equ 259:2948-2980, 2015; Oka in J Math Anal Appl 473:382-407, 2019) for the aim of addressing the existence and uniqueness of local and global mild solutions, on the Heisenberg group H-d, of the time-fractional Navier-Stokes system with time derivative of order alpha is an element of (0,1). The proof relies on Schaefer's fixed point theorem.
