Mathematical and numerical analysis of a stratigraphic model [PDF]

open access: bronzeESAIM: Mathematical Modelling and Numerical Analysis, 2004
Summary: We consider a multi-lithology diffusion model used in stratigraphic modelling to simulate large scale transport processes of sediments described as a mixture of \(L\) lithologies. This model is a simplified one for which the surficial fluxes are proportional to the slope of the topography and to a lithology fraction with unitary diffusion ...

Raman laser: mathematical and numerical analysis of a model [PDF]

open access: bronzeESAIM: Mathematical Modelling and Numerical Analysis, 2004
The paper considers a model of a multi-step (multi-frequency) Raman laser in a finite cavity. A system of evolution equations for amplitudes of the forward and backward waves at the \(i\)-th frequency, \(F_i\) and \(B_i\), is transformed into a system resembling the classical Lotka-Volterra model: \[ F_i' = -\alpha_i+\sum_{j=1}^nG_{ij}(F_j+B_j)F_i, \] \

Conservative stochastic differential equations: Mathematical and numerical analysis [PDF]

open access: hybridMathematics of Computation, 2009
We consider stochastic differential equations on the whole Euclidean space possessing a scalar invariant along their solutions. The stochastic dynamics therefore evolves on a hypersurface of the ambient space. Using orthogonal coordinate systems, we show the existence and uniqueness of smooth solutions of the Kolmogorov equation under some ellipticity ...

Solving the stokes problem on a massively parallel computer

open access: yesMathematical Modelling and Analysis, 2001
We describe a numerical procedure for solving the stationary two‐dimensional Stokes problem based on piecewise linear finite element approximations for both velocity and pressure, a regularization technique for stability, and a defect‐correction ...
