Ricci-flat supertwistor spaces
Ulf Lindstrom, Martin Rocek, Rikard von Unge
We show that supertwistor spaces constructed as a Kahler quotient of a hyperkahler cone (HKC) with equal numbers of bosonic and fermionic coordinates are Ricci-flat, and hence, Cal…

First-order supersymmetric sigma models and target space geometry
Andreas Bredthauer, Ulf Lindstrom, Jonas Persson
We study the conditions under which N=(1,1) generalized sigma models support an extension to N=(2,2). The enhanced supersymmetry is related to the target space complex geometry. Co…
