Property (T) for groups acting on simplicial complexes through taking an ``average'' of Laplacian eigenvalues
Summary: This article generalizes the \textit{A. Żuk}'s criterion for property (T) [C. R. Acad. Sci., Paris, Sér. I 323, No. 5, 453--458 (1996; Zbl 0858.22007)] and gives new criteria for property (T) (and for vanishing of higher \(L^2\)-cohomologies).
