dc.description.abstract	Four-dimensional manifolds with changing signature are obtained by taking the large N limit of fuzzy CP2 solutions to a Lorentzian matrix model. The regions of Lorentzian signature give toy models of closed universes which exhibit cosmological singularities. These singularities are resolved at finite N, as the underlying CP2 solutions are expressed in terms of finite matrix elements.	en_US
