Evaluation of data driven low-rank matrix factorization for accelerated solutions of the Vlasov equation

Bhavana Jonnalagadda, Stephen Becker

Low-rank methods have shown success in accelerating simulations of a collisionless plasma described by the Vlasov equation, but still rely on computationally costly linear algebra…
