Predicting Feynman periods in ϕ 4-theory
Journal of High Energy PhysicsWe present efficient data-driven approaches to predict the value of subdivergence-free Feynman integrals (Feynman periods) in ϕ 4-theory from properties of the underlying Feynman graphs, based on a statistical examination of almost 2 million graphs.

Approximation of an Optimal BV -Control Problem in the Coefficient for the p(x)-Laplace Equation
Journal of Optimization, Differential Equations and Their ApplicationsWe study a Dirichlet optimal control problem for a quasilinear monotone elliptic equation with the so-called weighted p(x)-Laplace operator. The coefficient of the p(x)-Laplacian, the weight u, we take as a control in BV (Ω) ∩ L∞(Ω).
