Mean curvature flow without singularities

Autor: Trumper, Mariel Sáez, Schnürer, Oliver C.

We study graphical mean curvature flow of complete solutions defined on subsets of Euclidean space. We obtain smooth long time existence. The projections of the evolving graphs also solve mean curvature flow. Hence this approach allows to smoothly fl

Uniqueness of self-similar solutions to the network flow in a given topological class

Autor: Trumper, Mariel Sáez

In this paper we study the uniqueness of expanding self-similar solutions to the network flow in a fixed topological class. We prove the result via the parabolic Allen-Cahn approximation proved in \cite{triodginz}. Moreover, we prove that any regular

Relaxation of the flow of triods by Curve Shortening Flow via the vector-valued parabolic Allen-Cahn equation

Autor: Trumper, Mariel Saez

In this paper we find solutions $u_\epsilon$ to a certain class of vector-valued parabolic Allen-Cahn equation that as $\epsilon \to 0$ develops as interface a given triod evolving under curve shortening flow.

Report

Existence of a solution to a vector-valued Allen-Cahn equation with a three well potential

Autor: Trumper, Mariel Saez

In this paper we prove existence of a vector-valued solution $v$ to -\Delta v +\frac{\nabla_v W(v)}{2}&=0, \lim_{r\to \infty}v(r \cos\theta,r\sin\theta)&= c_i \hbox{for} \theta \in (\theta_{i-1}, \theta_i), where $W:\rr^2\to \rr$ is non-negative func

Haciendo género con pizarras: aportes de la antropología simétrica al estudio del género en la investigación matemática

Autor: Fernando Valenzuela, María Isabel Cortéz, Mariel Sáez

Publikováno v: Estudios Públicos. :1-20

En este artículo revisitamos el libro de Bruno Latour, Nunca fuimos modernos. Ensayos de antropología simétrica (NFM), publicado originalmente en 1991, en que el autor inició su exploración de las repercusiones del programa de una sociología de

On the evolution by fractional mean curvature

Autor: Enrico Valdinoci, Mariel Sáez

Publikováno v: Communications in Analysis and Geometry. 27:211-249

In this paper we study smooth solutions to a fractional mean curvature flow equation. We establish a comparison principle and consequences such as uniqueness and finite extinction time for compact solutions. We also establish evolutions equations for

Fractional Laplacians and extension problems: the higher rank case

Autor: María del Mar González, Mariel Sáez

The aim of this paper is two-fold: first, we look at the fractional Laplacian and the conformal fractional Laplacian from the general framework of representation theory on symmetric spaces and, second, we construct new boundary operators with good co
