The logarithmic delay of KPP fronts in a periodic medium
Francois Hamel, James Nolen, Jean-Michel Roquejoffre +1
We consider solutions of the KPP-type equations with a periodically varying reaction rate, and compactly supported initial data. It has been shown by M. Bramson in the case of the…
Rarefaction pulses for the Nonlinear Schrodinger Equation in the transonic limit
David Chiron, Mihai Maris
We investigate the properties of finite energy travelling waves to the nonlinear Schrodinger equation with nonzero conditions at infinity for a wide class of nonlinearities. In spa…
Propagation in Fisher-KPP type equations with fractional diffusion in periodic media
Xavier Cabre, Anne-Charline Coulon, Jean-Michel Roquejoffre
We are interested in the time asymptotic location of the level sets of solutions to Fisher-KPP reaction-diffusion equations with fractional diffusion in periodic media. We show tha…
Blow up for the critical gKdV equation III: exotic regimes
Yvan Martel, Frank Merle, Pierre Raphael
We consider the blow up problem in the energy space for the critical (gKdV) equation in the continuation of part I and part II. We know from part I that the unique and stable blow…
Global existence of solutions to a parabolic-elliptic chemotaxis system with critical degenerate di ffusion
Elissar Nasreddine
This paper is devoted to the analysis of non-negative solutions for a degenerate parabolic-elliptic Patlak-Keller-Segel system with critical nonlinear diffusion in a bounded domain…
Convergence to Scattering States in the Nonlinear Schrödinger Equation
Pascal Bégout
In this paper, we consider global solutions of the following nonlinear Schrödinger equation in with $(α\in(0,\infty…
