Extremal Spanning Trees in Product Grid Graphs

Jiechen Zhang

We compare spanning-tree counts at a fixed number of vertices for Cartesian products of paths $P_{r}$ , $r \geq 1$ , or cycles $C_{s}$ , $s \geq 3$ . With the number $d$ of factors fixed, an equ…

Spanning-Tree Maximization Forces Isoperimetry in the Square Lattice

Jiechen Zhang

We determine which connected sets of $N$ vertices in the square lattice support the most spanning trees, using all lattice edges between the chosen vertices. Every maximizer minimi…
