Semi-discrete optimal transport methods for the semi-geostrophic equations [PDF]
Calculus of Variations and Partial Differential Equations, 2022 AbstractWe give a new and constructive proof of the existence of global-in-time weak solutions of the 3-dimensional incompressible semi-geostrophic equations (SG) in geostrophic coordinates, for arbitrary initial measures with compact support. This new proof, based on semi-discrete optimal transport techniques, works by characterising discrete ...

, 2021 We study the numerical approximation of numerous processes, solutions of nonlinear stochastic differential equations, that appear in various applications such as financial mathematics and population dynamics. Between the investigated models are the CIR process, also known as the square root process, the constant elasticity of variance process CEV, the ...

Numerical evaluation of fractional Tricomi-type model arising from physical problems of gas dynamics
Journal of Advanced Research, 2020 This paper deals with approximating the time fractional Tricomi-type model in the sense of the Caputo derivative. The model is often adopted for describing the anomalous process of nearly sonic speed gas dynamics.

Note on a W1,∞(L2)-error estimate of a nonlinear finite volume scheme for a semi-linear heat equation [PDF]
Arab Journal of Mathematical Sciences, 2021 We consider, as discretization in space, the nonconforming mesh developed in SUSHI (Scheme Using Stabilization and Hybrid Interfaces) developed in Eymard et al. (2010) for a semi-linear heat equation.
