Construction of Supergravity Backgrounds with a Dilaton Field
Noriko Nakayama, Katsuyuki Sugiyama
A new class of non-compact Kahler backgrounds accompanied by a non-constant dilaton field is constructed as a supergravity solution. It is interpreted as a complex line bundle over…

N=2 Supersymmetric Sigma Models and D-branes
Noriko Nakayama, Katsuyuki Sugiyama
We study D-branes of N=2 supersymmetric sigma models. Supersymmetric nonlinear sigma models with 2-dimensional target space have D0,D1,D2-branes, which are realized as A-,B-type su…
