Supermanifolds from Feynman graphs
Matilde Marcolli, Abhijnan Rej
We generalize the computation of Feynman integrals of log divergent graphs in terms of the Kirchhoff polynomial to the case of graphs with both fermionic and bosonic edges, to whic…
Rigid Surface Operators
Sergei Gukov, Edward Witten
Surface operators in gauge theory are analogous to Wilson and 't Hooft line operators except that they are supported on a two-dimensional surface rather than a one-dimensional curv…
Removal of violations of the Master Ward Identity in perturbative QFT
Ferdinand Brennecke, Michael Duetsch
We study the appearance of anomalies of the Master Ward Identity, which is a universal renormalization condition in perturbative QFT. The main insight of the present paper is that…
Heat trace asymptotics defined by transfer boundary conditions
Peter Gilkey, Klaus Kirsten, Dmitri Vassilevich
We compute the first 5 terms in the short-time heat trace asymptotics expansion for an operator of Laplace type with transfer boundary conditions using the functorial properties of…
Noncommutative gerbes and deformation quantization
Paolo Aschieri, Igor Bakovic, Branislav Jurco +1
We define noncommutative gerbes using the language of star products. Quantized twisted Poisson structures are discussed as an explicit realization in the sense of deformation quant…
