Contribution

It presents a new percolation model with equal edge times on lines, proves convergence and shape theorems, and extends analysis to infinite passage times.

Findings

Established a point-to-point convergence theorem and identified the time constant.

Proved a shape theorem with the limiting shape as the L1 diamond.

Extended results to cases with infinite passage times.

Abstract

We investigate a novel first-passage percolation model, referred to as the Brochette first-passage percolation model, where the passage times associated with edges lying on the same line are equal. First, we establish a point-to-point convergence theorem, identifying the time constant. In particular, we explore the case where the time constant vanishes and demonstrate the existence of a wide range of possible behaviours. Next, we prove a shape theorem, showing that the limiting shape is the $L^1$ diamond. Finally, we extend the analysis by proving a point-to-point convergence theorem in the setting where passage times are allowed to be infinite.
