IBISMLの皆様

東京大学の小池です。

1月のAsia-Pacific Seminar in Probability and Statistics (APSPS)の告知です。

Date: 18 January (Wed), 2023
Time: 14:30 (Japan)
Speaker: Rongfeng Sun, Department of Mathematics, NUS, Singapore
Title: A new correlation inequality for Ising models with external fields
Abstract: We study ferromagnetic Ising models on finite graphs with an
inhomogeneous external field. We show that the influence of boundary
conditions on any given spin is maximised when the external field is
identically 0. One corollary is that spin-spin correlation is
maximised when the external field vanishes. In particular, the random
field Ising model on Z^d, d ≥ 3, exhibits exponential decay of
correlations in the entire high temperature regime of the pure Ising
model. Another corollary is that the pure Ising model on Z^d, d ≥ 3,
satisfies the conjectured strong spatial mixing property in the entire
high temperature regime.
Based on joint work with Jian Ding and Jian Song.

Asia-Pacific Seminar in Probability and Statistics


The seminar is created as a permanent forum for good research in the
field. It is our way to counterbalance the restrictions imposed on us
by the pandemic and to still promote scientific exchange and
cooperation. It will run using Zoom.

Topics include probabilistic models for natural phenomena, stochastic
processes and statistical inference, statistical problems in
high-dimensional spaces, asymptotic methods, statistical theory of
diversity. At the same time, there are no restrictions on other topics
of the seminar presentations.

The emphasis is on novelty, but even more so, on beauty, and clarity.
Where possible, heuristic arguments are preferred to presentation of
technical details. Speakers are encouraged to discuss meaningful
applications and open problems. Good reviews are welcome.
Presentations should be accessible to good postgraduate students in
probability and mathematical statistics.

The Board of the Seminar consists of

Sanjay Chaudhuri (NUS, Singapore),
Mark Holmes (University of Melbourne, currently at UBC, Vancouver),
Estate Khmaladze (VUW, Wellington),
Krishanu Maulik (ISI, Kolkata)
Spiro Penev (UNSW, Australia),
Lijiang Yang (Tsinghua University, Beijing),
Nakahiro Yoshida (University of Tokyo, Tokyo).

The Board is responsible for the programme. All of us will be happy to
discuss details with potential speakers. Please, e-mail us if you
would like to contribute -- addresses readily obtainable on the web.

We plan to run seminars on Wednesdays, once a month. Time will vary in
between UTC+10 - UTC+12 (India) and UTC+17 - UTC+20 (New Zealand).
Specific dates will be given on the web-page
