In this paper, we develop a new sixth-order finite difference central weighted essentially non-oscillatory (WENO) scheme with Z-type nonlinear weights for degenerate parabolic equations. The centered polynomial is introduced the WENO reconstruction to avoid negative linear weights. We choose based on $$L^2$$ -norm smoothness indicators, yielding less computational cost. It also confirmed that p...

Abstract This paper presents an iterative formulation to compute the central moments of matrix Fisher distribution on three dimensional special orthogonal group up arbitrary order.

Numerical relativity simulations are the only way to calculate exact gravitational waveforms from binary neutron star mergers and design templates for gravitational-wave astronomy. The accuracy of these numerical calculations is critical in quantifying tidal effects near merger that currently one main sources uncertainty waveforms. In this work, we explore use an entropy-based flux-limiting sch...
