Difference Equations in Spaces of Regular Functions: A Tribute To Salvatore Pincherle
Download Full Text
Pincherle studies the surjectivity of a difference operator with constant coefficients in the space of holomorphic functions. In this paper, we discuss how this work can be rephrased in the context of modern functional analysis and we conclude by extending his results and we show that difference equations act surjectively on the space of quaternionic regular functions.
