[ABE-L] Próximo seminário (online) de probabilidade

[Maria Eulalia Vares]

*Probability Webinar -   IM-UFRJ *



Dear colleagues,

Our next online seminar will be held on Monday, *June 28, * from *3 p.m. to
4 p.m*. (Rio de Janeiro local time)

The GoogleMeet link for the seminar is https://meet.google.com/uew-ehhn-kby


Speaker:   *Lucas Affonso (IME-USP)*

Title: *Long-range Ising model and decaying fields- a contour approach*

Abstract: In 1982, Fröhlich and Spencer solved a long-standing conjecture
about phase transition in a one-dimensional long-range Ising model for [image:
1/r^2] interaction energy. After that, Cassandro, Ferrari, Merola, and
Presutti extended the contour argument for other decays [image: \alpha].
In this talk, we address the multidimensional long-range Ising model,
showing that a contour argument holds for all decays [image: \alpha> d]. As
an application, we will show how our techniques can be used to study phase
transition when the model has a decaying magnetic field.


The talk is based on joint work with Rodrigo Bissacot, Eric O. Endo, and
Satoshi Handa.



All the talks are held in English.

The videos of the online seminars held in 2020 are available at

For the 2021 series, a few days after each meeting the video should be
available at http://www.dme.ufrj.br/?page_id=3027



Thanks for circulating this information.

Sincerely,
