Supersymmetric Cycles in Exceptional Holonomy Manifolds and Calabi-Yau 4-Folds
K. Becker, M. Becker, D. R. Morrison +3
We derive in the SCFT and low energy effective action frameworks the necessary and sufficient conditions for supersymmetric cycles in exceptional holonomy manifolds and Calabi-Yau…

String Theory on K3 Surfaces
P. S. Aspinwall, D. R. Morrison
The moduli space of N=(4,4) string theories with a K3 target space is determined, establishing in particular that the discrete symmetry group is the full integral orthogonal group…

Spacetime Topology Change: The Physics of Calabi-Yau Moduli Space
P. S. Aspinwall, B. R. Greene, D. R. Morrison
We review recent work which has significantly sharpened our geometric understanding and interpretation of the moduli space of certain =2 superconformal field theories. This has…
