Bifurcation and global continuation of travelling-rotating Schrödinger maps on the sphere

Juan Carlos Sampedro, Luis Vega

We study travelling-rotating solutions of the Schrödinger map equation into the sphere, viewed as tangent profiles of rigid vortex filaments. Two first integrals reduce the profil…

Note on infinite-dimensional -spaces

Daniel L. Rodríguez-Vidanes, Juan Carlos Sampedro

We prove that, for every , the -space of Baker's measure on is isometrically isomorphic to in ZFC…

Distributional embeddings of the first limit Bourgain-Rosenthal-Schechtman space

Juan Carlos Sampedro

We classify the distributional self-embeddings of the centered first limit Bourgain-Rosenthal-Schechtman space , . Using a Boolean rigidity principle for it…

A bifurcation theory approach to the nonlocal Kuramoto-Sivashinsky equation

Pablo Cubillos, Rafael Granero-Belinchón, Juan Carlos Sampedro

We study the nonlocal Kuramoto-Sivashinsky equation on the one-dimensional torus, \[ u_t+u u_x=Λ^{r}u-\varepsilon Λ^{s}u,\qquad x\in\mathbb T, \] where , , $r…

Periodic solutions to nonlocal pseudo-differential equations. A bifurcation theoretical perspective

Juan Carlos Sampedro

In this paper we use abstract bifurcation theory for Fredholm operators of index zero to deal with periodic even solutions of the one-dimensional equation $\mathcal{L}u=λu+|u|^{p}…

Global Leray-Schauder continuation for Fredholm operators

Julián López-Gómez, Juan Carlos Sampedro

This paper ascertains the global behavior of the forward and backward branches of solutions provided by the Leray-Schauder continuation theorem for orientable Fredh…
