Classical BV theories on manifolds with boundary
[article]
2012
arXiv
pre-print
In particular, we connect the BV construction in the bulk with the BFV construction on the boundary and we develop its extension to strata of higher codimension in the case of manifolds with corners. ...
In this paper we extend the classical BV framework to gauge theories on spacetime manifolds with boundary. ...
Classically it extends to higher categories, and we anticipate that quantum counterparts of such extensions are higher category versions of topological quantum field theories. ...

We are naturally led to conjecture the existence of new dualities relating spaces with different singular geometries and fluxes. ...
These vacua can be realized in a number ways: the perturbative constructions we study include toroidal compactifications of the heterotic/type I strings, asymmetric orbifolds, and orientifolds. ...
The descriptions we give of the lattices can be inferred from the descriptions in [37] using techniques from [57] .
A related geometric structure appears in [69] . ...
