Lanza de Cristoforis, Massimo; Musolino, Paolo A real analyticity result for a nonlinear integral operator. (English) Zbl 1278.47057 J. Integral Equations Appl. 25, No. 1, 21-46 (2013). This paper is concerned with a nonlinear integral operator which involves a Nemytskij type operator and which appears in the applications as a pull-back of layer potential operators. The authors prove an analyticity result in Schauder spaces by splitting the operator into the composition of a nonlinear operator acting into Roumieu classes and a composition operator.
