%0 Journal Article %T Hypermultiplet Moduli Space and Three Dimensional Gauge Theories %A Moshe Rozali %J Physics %D 1999 %I arXiv %R 10.1088/1126-6708/1999/12/013 %X We establish a relation, conjectured recently by E. Witten, between the hypermultiplet moduli space in compactifications of the heterotic string on an A-D-E singularities, and the moduli spaces of three dimensional pure gauge theories with the corresponding A-D-E gauge groups. It is possible to add a bounded number of heterotic fivebranes sitting in the singularity, while (in leading order in $\alpha'$) keeping the heterotic string perturbative. The corresponding hypermultiplet moduli space is given by the moduli space of a three dimensional gauge theory with matter. %U http://arxiv.org/abs/hep-th/9910238v1
