Characterization of distributions whose forward differences are exponential polynomials

J. M. Almira

Given ${h_{1}, \dots, h_{t}}$ a finite subset of $R^{d}$ , we study the continuous complex valued functions and the Schwartz complex valued distributions $f$ defined on $\mat…

Characterization of Polynomials as solutions of certain functional equations

J. M. Almira

Recently, the functional equation \[ \sum_{i=0}^mf_i(b_ix+c_iy)= \sum_{i=1}^na_i(y)v_i(x) \] with $x, y \in R^{d}$ and $b_{i}, c_{i} \in GL_{d} (C)$ , was studied by Alm…

On certain generalizations of the Levi-Civita and Wilson functional equations

J. M. Almira, E. V. Shulman

We study the functional equation \[ \sum_{i=1}^mf_i(b_ix+c_iy)= \sum_{k=1}^nu_k(y)v_k(x) \] with $x, y \in R^{d}$ and $b_{i}, c_{i} \in G L (d, R)$ , both in the classical con…
