Internal aggregation models with multiple sources and obstacle problems on Sierpinski gaskets

Uta Freiberg, Nico Heizmann, Robin Kaiser +1

We consider the doubly infinite Sierpinski gasket graph $S{G}_0$, rescale it by factor $2^{-n}$, and on the rescaled graphs $S{G}_n=2^{-n}S{G}_0$, for every $n\in \mathbb{N}$, we investi…
