Numerical multi-loop calculations with the program SecDec [PDF]
, 2014 SecDec is a program which can be used for the evaluation of parametric integrals, in particular multi-loop integrals. For a given set of propagators defining the graph, the program constructs the graph polynomials, factorizes the endpoint singularities ...

Quadratically-Regularized Optimal Transport on Graphs
, 2018 Optimal transportation provides a means of lifting distances between points on a geometric domain to distances between signals over the domain, expressed as probability distributions. On a graph, transportation problems can be used to express challenging

Journal of Combinatorial Theory, Series B, 1971 AbstractThis paper is a continuation of [1] and we shall use the same terminology. The main result of this part is the following: Suppose that the automorphism group of a connected graph of valency p + 1, p a prime, has a subgroup which acts as a regular permutation group on the set of s-arcs of the graph. Then s ≤ 7 and s ≠ 6.

On orbital regular graphs and frobenius graphs
Discrete Mathematics, 1998 A group is a Frobenius group if it acts transitively but not freely on a set such that no two elements are fixed by a non-trivial element of the group. An orbital-regular graph is a finite graph whose automorphism group has a subgroup which is transitive on the edges and contains no element which fixes two vertices.

A simplifying feature of the heterotic one loop four graviton amplitude
Physics Letters B, 2018 We show that the weight four modular graph functions that contribute to the integrand of the t8t8D4R4 term at one loop in heterotic string theory do not require regularization, and hence the integrand is simple.

Light Field Super-Resolution Via Graph-Based Regularization
, 2017 Light field cameras capture the 3D information in a scene with a single exposure. This special feature makes light field cameras very appealing for a variety of applications: from post-capture refocus, to depth estimation and image-based rendering ...

Regular factors in regular graphs
Discrete Mathematics, 1993 The author shows that a \(k\)-regular \((k-1)\)-edge-connected graph with an even number of vertices has an \(m\)-factor not containing \(k-m\) arbitrarily prescribed edges whenever \(1\leq m\leq k-1\). This was known only for \(m=1\) or \(k-1\). Also the sharpness of this result and some corollaries are given.
