Numerical evaluation of master integrals from differential equations
, 2002 The 4-th order Runge-Kutta method in the complex plane is proposed for numerically advancing the solutions of a system of first order differential equations in one external invariant satisfied by the master integrals related to a Feynman graph.

Spectrum‐sensing algorithm based on graph feature fusion
IET Radar, Sonar & NavigationGraph‐based spectrum sensing in noisy environments has major implications for civilian and military signal processing applications. However, existing algorithms suffer from high computational complexity and performance deterioration at low signal‐to ...

Constructing and Classifying Fully Irreducible Outer Automorphisms of Free Groups
, 2012 The main theorem of this document emulates, in the context of Out(F_r) theory, a mapping class group theorem (by H. Masur and J. Smillie) that determines precisely which index lists arise from pseudo-Anosov mapping classes.

Yangian symmetry for bi-scalar loop amplitudes
Journal of High Energy Physics, 2018 We establish an all-loop conformal Yangian symmetry for the full set of planar amplitudes in the recently proposed integrable bi-scalar field theory in four dimensions. This chiral theory is a particular double scaling limit of γ-twisted weakly coupled N=

A Note on Dual MHV Diagrams in N=4 SYM
, 2010 Recently a reformulation of the MHV diagram method in N=4 supersymmetric Yang-Mills theory in momentum twistor space was presented and was shown to be equivalent to the perturbative expansion of the expectation value of a supersymmetric Wilson loop in ...

From modular graph forms to iterated integrals
Journal of High Energy PhysicsModular graph forms are a class of non-holomorphic modular forms that arise in the low-energy expansion of genus-one closed string amplitudes. In this work, we introduce a systematic procedure to convert lattice-sum representations of modular graph forms

Towards quantum gravity with neural networks: solving the quantum Hamilton constraint of U(1) BF theory [PDF]
Classical and quantum gravityIn the canonical approach of loop quantum gravity, arguably the most important outstanding problem is finding and interpreting solutions to the Hamiltonian constraint.
