Douglas–Rachford methods are studied on Hadamard manifolds
What the study found The study proposes inertial and non-inertial Douglas–Rachford algorithms for minimizing the sum of two geodesically convex functions on Hadamard manifolds, which are complete, nonpositively curved spaces. The authors also introduce parallel Douglas–Rachford type algorithms for problems with multiple summands and apply them to generalized Heron problems. Why the authors say this…
PineAPPL and MATRIX are linked for NNLO interpolation grids
What the study found The study presents an interface between PineAPPL and Matrix that can calculate fully differential cross sections as interpolation grids with next-to-next-to-leading order (NNLO) accuracy in quantum chromodynamics (QCD, the theory of strong interactions) and next-to-leading order (NLO) accuracy in electroweak (EW) theory. Why the authors say this matters The authors say…
