4月のAsia-Pacific Seminar in Probability and Statistics (APSPS)の告知です。

Date: 20 April (Wed), 2022
Time: 14:30 (Japan)
Speaker: Rahul Roy, Indian Statistical Institute, Delhi
Title: Drainage networks and the Brownian web
Abstract: River basin geomorphology is a very old subject of study
initiated by Horton (1945). Various statistical models of drainage
networks have been proposed. Each such model is a random directed
graph with its own nuances.
In recent years physicists have been interested in these models
because of the commonality of such branching networks in many areas of
statistical physics (see Rodríguez-Iturbe and Rinaldo (1997) for a
detailed survey).
We discuss the geometric features of two such models and also their
scaling limit. The scaling limit of this model is the Brownian web,
which has lately been the focus of extensive study among probabilists.
In particular, from this scaling limit we establish rigorously the
empirical observed relation, Hack's law, between the length of a
stream up to a divide and the  area of the drainage region till the
divide.

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),
Masanobu Taniguchi (Waseda University, Tokyo),
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
