Application of approximate matrix factorization to high order linearly implicit Runge-Kutta methods
Hong Zhang, Adrian Sandu, Paul Tranquilli
Linearly implicit Runge-Kutta methods with approximate matrix factorization can solve efficiently large systems of differential equations that have a stiff linear part, e.g. reacti…

A Derivative-Free Trust Region Framework for Variational Data Assimilation
Elias D. Nino, Adrian Sandu
This study develops a hybrid ensemble-variational approach for solving data assimilation problems. The method, called TR-4D-EnKF, is based on a trust region framework and consists…

Exponential-Krylov methods for ordinary differential equations
Paul Tranquilli, Adrian Sandu
This paper develops a new class of exponential-type integrators where all the matrix exponentiations are performed in a single Krylov space of low dimension. The new family, called…
