Analytic general solutions of nonlinear second-order $q$-difference equations with a double characteristic value

open access: yesRendiconti del Seminario Matematico della Universita di Padova, 2023
As far as the author knows it seems that an existence theorem of a solution of a general nonlinear q-difference equation is not known. In this paper we will investigate a nonlinear second order q-difference equation whose characteristic equation has only

On the convergence of generalized power series solutions of q-difference equations [PDF]

open access: yes, 2021
A sufficient condition for the convergence of a generalized formal power series solution to an algebraic q-difference equation is provided. The main result leans on a geometric property related to the semi-group of (complex) power exponents of such a ...

Entire solutions for several complex partial differential-difference equations of Fermat type in ℂ2

open access: yesOpen Mathematics, 2021
By utilizing the Nevanlinna theory of meromorphic functions in several complex variables, we mainly investigate the existence and the forms of entire solutions for the partial differential-difference equation of Fermat type α∂f(z1,z2)∂z1+β∂f(z1,z2)∂z2m+f(

Elementary exact calculations of degree growth and entropy for discrete equations [PDF]

open access: yes, 2017
Second-order discrete equations are studied over the field of rational functions C(z)C(z), where z is a variable not appearing in the equation. The exact degree of each iterate as a function of z can be calculated easily using the standard calculations ...
