Perfect t-Embeddings of Uniformly Weighted Generalized Tower Graphs

Abstract: In this paper, we study sequences of perfect t-embeddings of a uniformly weighted family of graphs we call generalized tower graphs. We show that the embeddings of these graphs satisfy certain technical assumptions, in particular, the rigidity assumption of Berggren-Nicoletti-Russkikh. As a result, we confirm the convergence of the gradients of the height function fluctuations of these graphs to those of the Gaussian free field.
