Wave functions and properties of massive states in three-dimensional supersymmetric Yang-Mills theory [PDF]
, 2001 We apply supersymmetric discrete light-cone quantization (SDLCQ) to the study of supersymmetric Yang-Mills theory on R x S^1 x S^1. One of the compact directions is chosen to be light-like and the other to be space-like.
