Title: Regularisation by noise and notions of irregularity
June 26, 2020 (Friday) - 11:00 - zoom link: TBA

Abstract:
A natural question in the field of regularisation by noise phenomena
is to understand under which conditions on a path $w$, the additively
perturbed ODE $x'=b(x)+w'$ is well-posed, even when its unperturbed
counterpart $x'=b(x)$ is not. In order to answer this question,
Catellier and Gubinelli (SPA 2016) introduced the theory of nonlinear
Young integrals and the concept of $\rho$-irregularity of $w$; they
also proved that fBm paths are $\rho$-irregular. In this talk, I will
first review their work and then present its more recent extensions.
The property of $\rho$-irregularity can be linked to the regularity of
the local time of $w$ and, in the case of Gaussian processes, can be
established under a suitable local non-determinism (LND) condition.
Moreover, it can be shown that $\rho$-irregular paths are necessarily
nowhere $\alpha$-Holder continuous, for suitable values
$\alpha=\alpha(\rho)$. This gives a rigorous proof of the frequently
observed paradigm "the rougher the noise, the better the
regularisation".
Based on joint works with Massiliano Gubinelli.

Title: The Widom-Rowlinson model: metastability, mesoscopic and microscopic
fluctuations for the critical droplet
3 JULY (Friday) - 11:00 - zoom link: TBA
The link and password to access the seminar will be available at the
following webpage
https://www.math.unipd.it/~bianchi/seminari/
Abstract:
We introduce the equilibrium Widom-Rowlinson model on a two-dimensional
finite torus in which the energy of a particle configuration is attractive
and determined by the union of small discs centered at the positions of the
particles. We then discuss the metastable behaviour of a dynamic version of
the WR model. This means that the particle configuration is viewed as a
continuous time Markov process where particles are randomly created and
annihilated as if the outside of the torus were an infinite reservoir with
a given chemical potential. In particular, we start with the empty torus
and are interested in the first time when the torus is fully covered by
discs in the regime at low temperature and when the chemical potential is
supercritical. In order to achieve the transition from empty to full, the
system needs to create a sufficiently large droplet, called critical
droplet, which triggers the crossover. We compute the distribution of the
crossover time and identify the size and the shape of the critical droplet.
The analysis relies on a mesoscopic and microscopic description of the
surface of the critical droplet. It turns out that the critical droplet is
close to a disc of a certain deterministic radius, with a boundary that is
random and consists of a large number of small discs that stick out by a
small distance. We will show how the analysis of surface fluctuations in
the WR model allows us to derive the leading order term of the condensation
time and also the correction order term.
This is a joint work with Frank den Hollander (Leiden), Sabine Jansen
(Munich) and Roman Kotecky (Prague & Warwick).

offers 5 PhD positions (75% TVL E 13, about 1700 EUR p.m. after taxes,
social security...) for 3 years starting
October 1, 2020, or soon thereafter.
Funded by the Deutsche Forschungsgemeinschaft (DFG), the IRTG is a joint
research initiative of the stochastic analysis group of FU, HU, TU and
WIAS Berlin with its counterpart at the University of Oxford. The
advertised positions will be based in Berlin and will offer ample
opportunities to interact also with members of the Oxford team, most
notably in a 6-months exchange.
Embedded in a truly international environment, the IRTG students will get
excellent research training in a structured programme focussing on
challenges at the mathematical foundations of Stochastic Analysis as well
as on challenges arising from its various applications, e.g., in physics,
biology, finance or data science. The combined expertise from the Berlin
and Oxford groups will provide a significant breadth in depth and fertile
ground for our students' ambitious research ideas.
Successful candidates will have an MSc degree (or equivalent) in
Mathematics (or a closely related field), strong knowledge of stochastic
analysis, and feel eager to engage in the exchange of ideas with the teams

-------- TITLE
Mathematics of shuffling
(https://www.math.unipd.it/news/mathematics-of-shuffling/ )
-------- ABSTRACT
The crux of a card trick performed with a deck of cards usually depends
on understanding how shuffles of the deck change the order of the cards.
By understanding which permutations are possible, one knows if a given
card may be brought into a certain position. The mathematics of
shuffling a deck of 2n cards with two ``perfect shuffles'' was studied
thoroughly by Diaconis, Graham and Kantor in 1983. I will report on our
efforts to understand a generalisation of this problem, with a so-called
``many handed dealer'' shuffling kn cards by cutting into k piles with n
cards in each pile and using k! possible shuffles.
A conjecture of Medvedoff and Morrison suggests that all possible
permutations of the deck of cards are achieved, as long as k is not 4
and n is not a power of k. We confirm this conjecture for three doubly
infinite families of integers, but the conjecture remains open. We
initiate a more general study of shuffle groups, which admit an
arbitrary subgroup of shuffles.
This is joint work with Carmen Amarra and Luke Morgan.
-------- SHORT BIO SPEAKER
Cheryl Praeger is Emeritus Professor of Mathematics at the University of
Western Australia. In 2007 she won an Australian Research Council
Federation Fellowship and in 2010-14 she served as inaugural Director of
the Centre for the Mathematics of Symmetry and Computation at UWA. Her
mathematical research work has transformed our understanding of how
groups act on large complex systems, through new theories,
constructions, algorithms and designs, which exploit the classification
of the finite simple groups.
Professor Praeger received BSc and MSc degrees from the University of
Queensland, a DPhil degree from the University of Oxford in 1973, and
has received honorary doctorates from Universities in six countries on
three continents. She has served on the Executive of the International
Mathematical Union and on the Council and Executive of the Australian
academy of Science. She is a former Vice President of the International
Commission for Mathematical Instruction, and former Foreign Secretary of
the Australian Academy of Science. She is Fellow of the American
Mathematical Society, an Honorary member of the London Mathematical
Society, and she was the first woman to be President of the Australian
Mathematical Society of which she is now an Honorary Life Member. In
2019 she was awarded the Prime Minister’s Prize for Science in
recognition of her incredible contribution to mathematics research and
education in Australia and around the world.
Professor Praeger has published more than 400 journal articles and five
research monographs, many of them with her students (30 PhD students, 10
research masters students, 21 postdoctoral research associates) and
research colleagues. She has played an active role supporting and
mentoring young scientists, especially women.
