Reflective hyperbolic 2-elementary lattices, K3 surfaces and hyperkahler varieties
arXiv:2209.09110
Abstract
We compute Coxeter diagrams of several ``large'' reflective even 2-elementary hyperbolic lattices and their maximal parabolic subdiagrams, and give some applications of these results to the theory of K3 surfaces and hyperkahler varieties.
