Rational normal forms and stability of small solutions to nonlinear Schrödinger equations
Joackim Bernier, Erwan Faou, Benoit Grebert
We consider general classes of nonlinear Schrödinger equations on the circle with nontrivial cubic part and without external parameters. We construct a new type of normal forms, na…
Efficient atom selection strategy for iterative sparse approximations
Clément Dorffer, Angélique Drémeau, Cedric Herzet
We propose a low-computational strategy for the efficient implementation of the "atom selection step" in sparse representation algorithms. The proposed procedure is based on simple…
Paracontrolled calculus and regularity structures
I. Bailleul, M. Hoshino
We start in this work the study of the relation between the theory of regularity structures and paracontrolled calculus. We give a paracontrolled representation of the reconstructi…
Young and rough differential inclusions
I. Bailleul, A. Brault, L. Coutin
We define in this work a notion of Young differential inclusion for an -Holder control , with , and give an existence result for such a diff…
A new general formula for the Cauchy Index on an interval with Subresultants
Daniel Perrucci, Marie-Françoise Roy
We present a new formula for the Cauchy index of a rational function on an interval using subresultant polynomials. There is no condition on the endpoints of the interval and the f…
Regularized numerical methods for the logarithmic Schrodinger equation
Weizhu Bao, Rémi Carles, Chunmei Su +1
We present and analyze two numerical methods for the logarithmic Schr{ö}dinger equation (LogSE) consisting of a regularized splitting method and a regularized conservative Crank-Ni…
