On the well-posedness of weakly hyperbolic equations with time dependent coefficients (1107.2565v2)
Published 13 Jul 2011 in math.AP
Abstract: In this paper we analyse the Gevrey well-posedness of the Cauchy problem for weakly hyperbolic equations of general form with time-dependent coefficients. The results involve the order of lower order terms and the number of multiple roots. We also derive the corresponding well-posedness results in the space of Gevrey Beurling ultradistributions.
