Existence and stability of multiple spot solutions for the gray-scott model in R^2 [PDF]

open access: yes, 2005
We study the Gray-Scott model in a bounded two dimensional domain and establish the existence and stability of {\bf symmetric} and {\bf asymmetric} multiple spotty patterns. The Green's function and its derivatives together with two nonlocal eigenvalue

Structure and Stability of the One-Dimensional Mapper [PDF]

open access: yesFoundations of Computational Mathematics, 2017
Given a continuous function $f: X\longrightarrow \mathbb{R}$ and a cover $\mathcal{I}$ of its image by intervals, the Mapper is the nerve of a refinement of the pullback cover $f^{-1}(\mathcal{I})$. This paper introduces a theoretical framework that establishes a correspondence between the Mapper to one of the Reeb graphs, which makes it possible to ...

Modification of three-dimensional transition in the wake of a rotationally oscillating cylinder [PDF]

open access: yes, 2010
A study of the flow past an oscillatory rotating cylinder has been conducted, where the frequency of oscillation has been matched to the natural frequency of the vortex street generated in the wake of a stationary cylinder, at Reynolds number 300.
