Odd connections on supermanifolds: Existence and relation with affine connections

AJ Bruce, J Grabowski - Journal of Physics A: Mathematical and …, 2020 - iopscience.iop.org
The notion of an odd quasi-connection on a supermanifold, which is loosely an affine
connection that carries non-zero Grassmann parity, is examined. Their torsion and curvature …

Singular superspaces

A Alldridge, J Hilgert, T Wurzbacher - Mathematische Zeitschrift, 2014 - Springer
We introduce a wide category of superspaces, called locally finitely generated, which
properly includes supermanifolds, but enjoys much stronger permanence properties, as are …
