Combinatorial Courant-Fischer-Weyl Minimax Principle on Cheeger $k$ -constants of Weighted Forests

Zijun Meng, Dong Zhang

We establish novel max-min and minimax characterizations of Cheeger $k$ -constants in weighted forests, thereby providing the first combinatorial analogue of the Courant-Fischer-Wey…
