Discrete Space-Time Wave Kernels on Regular Trees
Amar Bašić, Lejla Smajlović, Zenan Šabanac
We study the forward discrete space-time wave equation on the homogeneous -regular tree associated with a two-parameter generalized Laplacian. Under the natural no…

Discrete Bessel functions and discrete wave equation
Amar Bašić, Lejla Smajlović, Zenan Šabanac
In this paper, we study discrete Bessel functions which are solutions to the discretization of Bessel differential equations when the forward and the backward difference replace th…
