Positivity and discretization of Fredholm integral operators
Magdalena Nockowska-Rosiak, Christian Pötzsche
We provide sufficient conditions for vector-valued Fredholm integral operators and their commonly used spatial discretizations to be positive in terms of an order relation induced…

Sequences of positive homoclinic solutions to difference equations with variable exponent
Robert Stegliński, Magdalena Nockowska-Rosiak
We study the existence of infinitely many positive homoclinic solutions to a second-order difference equation on integers with -Laplacian. To achieve our goal we use the criti…
