Iterated remainder operator, tests for multiple convergence of series, and solutions of difference equations

J Migda - Advances in Difference Equations, 2014 - Springer
We establish some properties of iterations of the remainder operator which assigns to any
convergent series the sequence of its remainders. Moreover, we introduce the spaces of …

Qualitative approximation of solutions to difference equations
