On the convergence of generalized power series solutions of -difference equations

Renat Gontsov, Irina Goryuchkina, Alberto Lastra

A sufficient condition for the convergence of a generalized formal power series solution to an algebraic -difference equation is provided. The main result leans on a geometric p…
