Complex Geometry and Supersymmetry
I stress how the form of sigma models with (2, 2) supersymmetry differs
depending on the number of manifest supersymmetries. The differences correspond
to different aspects/formulations of Generalized K\"ahler Geometry.Comment: 9 pages, Proceedings of the Corfu Summer Institute 2011 School and

Complex geometry of quantum cones
The algebras obtained as fixed points of the action of the cyclic group
on the coordinate algebra of the quantum disc are studied. These can be
understood as coordinate algebras of quantum or non-commutative cones. The
following observations are made. First, contrary to the classical situation,
the actions of are free and the resulting algebras are homologically
smooth. Second, the quantum cone algebras admit differential calculi that have
all the characteristics of calculi on smooth complex curves. Third, the
corresponding volume forms are exact, indicating that the constructed algebras
describe manifolds with boundaries.Comment: 6 pages; submitted to the proceedings of Corfu Summer Institute 201
