Consistent $S^3$ reductions of six-dimensional supergravity

International audienceWe work out the consistent AdS3×S3 truncations of the bosonic sectors of both the six-dimensional N=(1,1) and N=(2,0) supergravity theories. They result in inequivalent three-dimensional half-maximal SO(4) gauged supergravities describing 32 propagating bosonic degrees of freedom apart from the nonpropagating supergravity multiplet. We present the full nonlinear Kaluza-Klein reduction formulas and illustrate them by explicitly uplifting a number of AdS3 vacua
