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 Space-Time Wave Kernels and Trace Identities on Regular Graphs
Amar Bašić, Lejla Smajlović, Zenan Šabanac
We study the discrete space-time wave equation on a -regular graph associated with the affine Laplace-type operator. For the forward time-difference scheme we derive exp…
