Anti-symmetric and Positivity Preserving Formulation of a Spectral Method for Vlasov-Poisson Equations
Opal Issan, Oleksandr Koshkarov, Federico D. Halpern +2
We analyze the anti-symmetric properties of a spectral discretization for the one-dimensional Vlasov-Poisson equations. The discretization is based on a spectral expansion in veloc…
Bayesian Inference and Global Sensitivity Analysis for Ambient Solar Wind Prediction
Opal Issan, Pete Riley, Enrico Camporeale +1
The ambient solar wind plays a significant role in propagating interplanetary coronal mass ejections and is an important driver of space weather geomagnetic storms. A computational…
Exact and optimal quadratization of nonlinear finite-dimensional non-autonomous dynamical systems
Andrey Bychkov, Opal Issan, Gleb Pogudin +1
Quadratization of polynomial and nonpolynomial systems of ordinary differential equations is advantageous in a variety of disciplines, such as systems theory, fluid mechanics, chem…
