RT Journal Article T1 Mathematical open problems in projected entangled pair states A1 Cirac, J. Ignacio A1 Garre Rubio, José A1 Pérez García, David AB Projected entangled pair states (PEPS) are used in practice as an efficient parametrization of the set of ground states of quantum many body systems. The aim of this paper is to present, for a broad mathematical audience, some mathematical questions about PEPS.
