MSTAR -- a fast parallelised algorithmically regularised integrator with minimum spanning tree coordinates
Antti Rantala, Pauli Pihajoki, Matias Mannerkoski +2
We present the novel algorithmically regularised integration method MSTAR for high accuracy () integrations of N-body systems using minimum spanning tree c…
Barycentric interpolation on Riemannian and semi-Riemannian spaces
Pauli Pihajoki, Matias Mannerkoski, Peter H. Johansson
Interpolation of data represented in curvilinear coordinates and possibly having some non-trivial, typically Riemannian or semi-Riemannian geometry is an ubiquitous task in all of…
A geometric approach to non-linear correlations with intrinsic scatter
Pauli Pihajoki
We propose a new mathematical model for -dimensional non-linear correlations with intrinsic scatter in -dimensional data. The model is based on Riemannian geometry, and is…
Ray-tracing and polarized radiative transfer in General Relativity
Pauli Pihajoki, Antti Rantala, Peter H. Johansson
We discuss the problem of polarized radiative transfer in general relativity. We present a set of equations suitable for solving the problem numerically for the case of an arbitrar…
