Wick rotation and the positivity of energy in quantum field theory
Maxim Kontsevich, Graeme Segal
We propose a new axiom system for unitary quantum field theories on curved space-time backgrounds, by postulating that the partition function and the correlators extend analyticall…
D-branes and K-theory in 2D topological field theory
Gregory W. Moore, Graeme Segal
This expository paper describes sewing conditions in two-dimensional open/closed topological field theory. We include a description of the G-equivariant case, where G is a finite g…
Heisenberg Groups and Noncommutative Fluxes
Daniel S. Freed, Gregory W. Moore, Graeme Segal
We develop a group-theoretical approach to the formulation of generalized abelian gauge theories, such as those appearing in string theory and M-theory. We explore several applicat…
The Uncertainty of Fluxes
Daniel S. Freed, Gregory W. Moore, Graeme Segal
In the ordinary quantum Maxwell theory of a free electromagnetic field, formulated on a curved 3-manifold, we observe that magnetic and electric fluxes cannot be simultaneously mea…
Twisted K-theory and cohomology
Michael Atiyah, Graeme Segal
We explore the relations of twisted K-theory to twisted and untwisted classical cohomology. We construct an Atiyah-Hirzebruch spectral sequence, and describe its differentials rati…
Twisted -theory
Michael Atiyah, Graeme Segal
Twisted complex -theory can be defined for a space equipped with a bundle of complex projective spaces, or, equivalently, with a bundle of C-algebras. Up to equivalence,…
