%0 Journal Article %T Strichartz estimates for partially periodic solutions to Schr£żdinger equations in 4d and applications %A Sebastian Herr %A Daniel Tataru %A Nikolay Tzvetkov %J Mathematics %D 2010 %I arXiv %R 10.1515/crelle-2012-0013 %X We consider the energy critical nonlinear Schr\"odinger equation on periodic domains of the form R^m x T^{4-m} with m=0,1,2,3. Assuming that a certain L^4 Strichartz estimate holds for solutions to the corresponding linear Schr\"odinger equation, we prove that the nonlinear problem is locally well-posed in the energy space. Then we verify that the L^4 estimate holds if m=2,3, leaving open the cases m=0,1. %U http://arxiv.org/abs/1011.0591v1
