Comparing Models of Rapidly Rotating Relativistic Stars Constructed by Two Numerical Methods We present the first direct comparison of codes based on two different numerical methods for constructing rapidly rotating relativistic stars. A code based on the Komatsu-Eriguchi-Hachisu (KEH) method (Komatsu et al. 1989), written by Stergioulas, is compared to the Butterworth-I

A Comparison of Numerical Methods for the Study of Star Cluster Dynamics We compare the results of three different numerical methods for computing the evolution of a spherical star cluster from a given initial state, under the influence of internal relaxation: the N-body integration, the Monte Carlo method, and the fluid-dynamical approach. The genera

The most commonly used stiff ODE solver isn't A-stable?!?!?
The most commonly used stiff ODE solver isn't A-stable?!?!? YouTube video by Chris Rackauckas

Your college professor teaches you "A-stable methods are required for stiff ODEs". But PSA, the most commonly used stiff ODE solvers (adaptive order BDF methods) are not A-stable. #sciml #numericalanalysis #diffeq

Bell polynomials have properties regarding scaling arguments by geometric progressions & values at sequences of factorials that radically simplify Traub's 1964 expression for all-equal-order-knot Lagrange-Hermite interpolants in the case of 2 knots. Convenient!

“That’s the beauty of limits: they don’t depend on the actual value of the function at the limit. They describe how the function behaves when it gets close to the limit.” - From Khan Academy

Suitability for SciComp vs ML is a key debate for Posits. There are trade-offs in error propagation & precision that must be carefully weighed depending on the specific application's requirements. #NumericalAnalysis 2/6

Key insight: Gaussian integration is highly accurate, precisely evaluating polynomials up to a certain degree based on the number of points. This precision was a core discussion point. #NumericalAnalysis 2/6

Numerical stability is a significant concern. The algorithm uses more additions/subtractions. Comments noted these operations can introduce more floating-point precision errors than multiplications, potentially impacting overall accuracy for sensitive computations. #NumericalAnalysis 3/7

Original post on mathstodon.xyz

Thanks to the Manchester NA group for organizing a seminar by David Watkins, one of the foremost experts on matrix eigenvalue algorithms. I find numerical linear algebra talks often too technical, but I could follow David's talk quite well even though I did not get everything, so thanks for that […]
