[ABE-L] Seminário (online) de probabilidade - IM-UFRJ - 11 de janeiro

[Maria Eulalia Vares]

*Probability Webinar -   IM-UFRJ *



Dear colleagues,

Our next online seminar will be held on Monday, *January 11*, 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:  *Julien Chevallier  (LJK, Université Grenoble Alpes)*

Title: *Brownian modules of continuité and diffusion approximation*

Abstract:  Garsia–Rodemich–Rumsey (1971) proved an inequality which has
been used to upper-bound the Brownian modules of continuity. In turn, this
upper-bound was used by T.G. Kurtz (1976) to prove a strong diffusion
approximation result for pure jump processes. However, this proof makes the
crucial assumption that jump rates are uniformly bounded.
The main objective of this talk is to show how to get rid of this
assumption starting back from GRR inequality. The second objective is to
show that this scheme of proof is robust to time scaling.



All the talks are held in English.
