The proof relies on Schaefer’s fixed point theorem. © 2021, The Author(s), under exclusive licence to Springer Nature Switzerland AG.enGlobal solutionNavier–Stokes equationsHeisenberg groupFractional time derivativeLocal and global existence of mild solutions of time-fractional Navier–Stokes system posed on the Heisenberg groupArticle
