Pin(d,d) covariance of pure spinor equations for supersymmetric vacua and Non-Abelian T-duality

Aybike Catal-Ozer, Emine Dirioz

In a supersymmetric compactification of Type II supergravity, preservation of $\mathcal{N}=1$ supersymmetry in four dimensions requires that the structure group of the generalized…
