An advanced leakage scheme for neutrino treatment in astrophysical simulations
Albino Perego, Ruben Cabezón, Roger Käppeli
We present an Advanced Spectral Leakage (ASL) scheme to model neutrinos in the context of core-collapse supernovae and compact binary mergers. Based on previous gray leakage scheme…
Weak convergence rates for spatial spectral Galerkin approximations of semilinear stochastic wave equations with multiplicative noise
Ladislas Jacobe de Naurois, Arnulf Jentzen, Timo Welti
Stochastic wave equations appear in several models for evolutionary processes subject to random forces, such as the motion of a strand of DNA in a liquid or heat flow around a ring…
Stability estimates for the regularized inversion of the truncated Hilbert transform
Rima Alaifari, Michel Defrise, Alexander Katsevich
In limited data computerized tomography, the 2D or 3D problem can be reduced to a family of 1D problems using the differentiated backprojection (DBP) method. Each 1D problem consis…
On stochastic differential equations with arbitrary slow convergence rates for strong approximation
Arnulf Jentzen, Thomas Müller-Gronbach, Larisa Yaroslavtseva
In the recent article [Hairer, M., Hutzenthaler, M., Jentzen, A., Loss of regularity for Kolmogorov equations, Ann. Probab. 43 (2015), no. 2, 468--527] it has been shown that there…
A Survey of Trefftz Methods for the Helmholtz Equation
Ralf Hiptmair, Andrea Moiola, Ilaria Perugia
Trefftz methods are finite element-type schemes whose test and trial functions are (locally) solutions of the targeted differential equation. They are particularly popular for time…
Trefftz discontinuous Galerkin methods on unstructured meshes for the wave equation
Andrea Moiola
We describe and analyse a space-time Trefftz discontinuous Galerkin method for the wave equation. The method is defined for unstructured meshes whose internal faces need not be ali…
Strong convergence rates for an explicit numerical approximation method for stochastic evolution equations with non-globally Lipschitz continuous nonlinearities
Arnulf Jentzen, Primož Pušnik
In this article we propose a new, explicit and easily implementable numerical method for approximating a class of semilinear stochastic evolution equations with non-globally Lipsch…
Weak convergence rates for Euler-type approximations of semilinear stochastic evolution equations with nonlinear diffusion coefficients
Arnulf Jentzen, Ryan Kurniawan
Strong convergence rates for time-discrete numerical approximations of semilinear stochastic evolution equations (SEEs) with smooth and regular nonlinearities are well understood i…
