However, in most cases,stationary Navier-Stokes problems were dealt with whereas instationary Navier-qStokes problems have been less studied. The L -approach to instationary Navier-Stokes problems is very important and convenient to analyze existence, uniquenessas well as strong energy inequality and partial regularity for solutions; to this end,the study of the Stokes operator is fundamental.Theaimofthisdissertationistogetresolventestimates, maximalregularityand∞boundedness ofH -calculus of Stokes operators in infinite cylindrical domains andtoapplythemtothestabilityofstationaryNavier-Stokesflowsininfinitecylindricaldomains.We start with a Stokes resolvent system in an infinite straight cylinder.
