[SeminarioDeProbabilidad] Hoy seminario de PPE 17h

[Liliana Peralta Hernández]

Estimada Comunidad,

Les recordamos que hoy, miércoles 16 de octubre, tendremos nuestra sesión
del Seminario de Probabilidad y Procesos Estocásticos. La cita es a las
17:00 hrs. en el Auditorio Alfonso Nápoles Gándara del Instituto de
Matemáticas.

En esta ocasión, Erin Beckman de Utah State nos ofrecerá una charla
titulada "A Branching Brownian Motion with Mean-Dependent Branch Rate". El
resumen es el siguiente:

We consider a branching Brownian motion model of a population evolving
under selective pressure. The rate at which a particle branches is
determined by the particle’s position relative to the average of the
population. Individuals that are more fit than average split in two, while
individuals that are less fit than average die. Our main result describes
the behavior of the particle system in the large-population limit by
connecting the process to the solution of a nonlocal reaction-diffusion
equation. Through this PDE connection, we show that the population’s
fitness distribution approximates a Gaussian traveling wave. This talk is
based on joint work with Sarah Penington.

¡Nos vemos!

Saludos Laura, Saraí y Liliana
