Flat Bundles on Function Manifolds and Evolution Equations in Quantum Field Theories
S. Srednyak
In this paper we discuss extensions of the canonical quantization procedure in quantum field theories. We focus specifically on S-matrix representation as a T-exponent. This extens…
Universal deformation of particle momenta space in perturbation theory
Stanislav Srednyak
We define an embedding of the space of complex momenta and masses in perturbation theory into a universal projective space. This embedding is natural in the sense of properties of…
Feynman integrals as flat bundles over the complement of Landau varieties
Stanislav Srednyak
We demonstrate that Feynman integrals of a fixed diagram form a flat vector bundle over the complement of Landau varieties that possesses a connection \begin{equation} \frac{\parti…
Perturbation theory in (2,2) signature
Stanislav Srednyak, George Sterman
We identify a natural analytic continuation in four dimensions from Minkowski signature to a signature with two time-like momentum components. For two, three and four-point diagram…
