Height function delocalisation on cubic planar graphs
Piet Lammers
The interest is in models of integer-valued height functions on shift-invariant planar graphs whose maximum degree is three. We prove delocalisation for models induced by convex ne…

Macroscopic behavior of Lipschitz random surfaces
Piet Lammers, Martin Tassy
The motivation for this article is to derive strict convexity of the surface tension for Lipschitz random surfaces, that is, for models of random Lipschitz functions from $\mathbb…
