second order differential operators with constant coefficients
A perturbation result for periodic layer potentials of general second order differential operators with constant coefficients
The authors show, in the \({\mathcal C}^{m,\alpha}\)-setting, the real analyticity of the nonlinear mappings related to the periodic layer potentials associated with families of fundamental solutions to second order elliptic differential operators with constant coefficients.NEWLINENEWLINEThe exploited methods are an extension and generalization of the approach proposed by the first author in a series of articles.
