A Holmgren type theorem for partial differential equations whose coefficients are Gevrey functions
Electronic journal of differential equations, Tome 2010 (2010)
In this article, we consider a uniqueness theorem of Holmgren type for p-th order Kovalevskaja linear partial differential equations whose coefficients are Gevrey functions. We prove that the only $C^p$-solution to the zero initial-valued problem is the identically zero function. To prove this result we use the uniqueness theorem for higher-order ordinary differential equations in Banach scales.
