Description

It was observed recently that multidimensional Mellin–Barnes integrals (Gustafson's integrals) arise naturally in studies of SL(2, R) spin chain models. We extend this analysis to noncompact S L ( 2 , C ) spin magnets and obtain an integral which generalizes Gustafson's integrals to the complex case. (paper)
