Feynman integrals from positivity constraints
Journal of High Energy Physics, 2023 We explore inequality constraints as a new tool for numerically evaluating Feynman integrals. A convergent Feynman integral is non-negative if the integrand is non-negative in either loop momentum space or Feynman parameter space.

Master integrals for bipartite cuts of three-loop photon self energy
Journal of High Energy Physics, 2021 We calculate the master integrals for bipartite cuts of the three-loop propagator QED diagrams. These master integrals determine the spectral density of the photon self energy.

A study of Feynman integrals with uniform transcendental weights and their symbology
Journal of High Energy Physics, 2022 Multi-loop Feynman integrals are key objects for the high-order correction computations in high energy phenomenology. These integrals with multiple scales may have complicated symbol structures, and we show that twistor geometries of closely related dual

Reduction of Feynman integrals in the parametric representation II: reduction of tensor integrals
European Physical Journal C: Particles and Fields, 2021 In a recent paper by the author (Chen in JHEP 02:115, 2020), the reduction of Feynman integrals in the parametric representation was considered. Tensor integrals were directly parametrized by using a generator method.

The integral of 2- refined rational neutrosophic functions [PDF]
Neutrosophic Sets and SystemsThe main objective of this paper is to study the integral of 2- refined rational neutrosophic functions, by providing direct rules that make it easy for us to find the integral of 2- refined rational neutrosophic functions, where the division of refined ...

Estimates for multiple stochastic integrals and stochastic Hamilton-Jacobi equations [PDF]
, 2004 We study stochastic Hamilton-Jacobi-Bellman equations and the corresponding Hamiltonian systems driven by jump-type Lévy processes. The main objective of the present paper is to show existence, uniqueness and a (locally in time) diffeomorphism ...

Constructing canonical Feynman integrals with intersection theory
Physics Letters B, 2021 Canonical Feynman integrals are of great interest in the study of scattering amplitudes at the multi-loop level. We propose to construct dlog-form integrals of the hypergeometric type, treat them as a representation of Feynman integrals, and project them
