Python Classes for Numerical Solution of PDE's

Asif Mushtaq, Trond Kvamsdal, Kåre Olaussen

We announce some Python classes for numerical solution of partial differential equations, or boundary value problems of ordinary differential equations. These classes are built on…

Automatic code generator for higher order integrators

Asif Mushtaq, Kåre Olaussen

Some explicit algorithms for higher order symplectic integration of a large class of Hamilton's equations have recently been discussed by Mushtaq \emph{et. al}. Here we present a P…

Higher order splitting methods with modified integrators for a class of Hamiltonian systems

Asif Mushtaq, Anne Kværnø, Kåre Olaussen

We discuss systematic extensions of the standard (St{ö}rmer-Verlet) splitting method for differential equations of Hamiltonian mechanics, with relative accuracy of order for…

Systematic Improvement of Splitting Methods for the Hamilton Equations

Asif Mushtaq, Anne Kværnø, Kåre Olaussen

We show how the standard (St{ö}rmer-Verlet) splitting method for differential equations of Hamiltonian mechanics (with accuracy of order for a timestep of length ) can be…

Very-high-precision solutions of a class of Schr{ö}dinger equations

Asif Mushtaq, Amna Noreen, Kåre Olaussen +1

We investigate a method to solve a class of Schr{ö}dinger equation eigenvalue problems numerically to very high precision (from thousands to a million of decimals). The memory…
