## High-dimensional Hoffman bound and extremal combinatorics

Accepted to Alg. Comb.

We generalize the Hoffman bound to simplicial complexes. We demonstrate our result by giving spectral proofs for Mantel’s theorem and for an optimal bound on $s$-wise intersecting families due to Frankl and Tokushige. As a new application, we give tight bounds on a question of Frankl about hypergraphs without extended triangles.
