==================================================
The first two talks will take place on Tuesday 20/10/20.
10-11:
*Clement Cosco(WIS) / Directed polymers on infinite graphs*
We study the directed polymer model for general infinite graphs and random
walks. We provide sufficient conditions for the existence or non-existence
of phase transitions in terms of properties of the graph and of the random
walk. We study in some detail (biased) random walk on various trees
including the Galton-Watson trees, and provide a range of other examples that
illustrate counter-examples to intuitive extensions of the simple random
walk on the lattice.
(Joint work with Inbar Seroussi and Ofer Zeitouni)
11-12:
*Ofer Zeitouni (WIS) / Minima of random polynomials*
We consider Gaussian random trigonometric polynomials and prove a limit
theorem for their minimum modulus on the unit circle. I will describe the
relevant background and various techniques employed in this and related
problems. Somewhat surprisingly, a crucial step in the proof involves a
characterization of Poisson processes due to Liggett, and its refinement
due to Biskup-Louidor. (Joint work with Oren Yakir, TAU)

Title: *Posterior asymptotics in Wasserstein metrics on the real line*
Zoom link:
https://us02web.zoom.us/j/88252069649?pwd=V2Z3b1UrZVVWNWZ4OXhydUtIakxpUT09
Meeting ID: 882 5206 9649
Passcode: 581405
Abstract: We use the class of Wasserstein metrics to study asymptotic
properties of posterior distributions. The first goal is to provide
sufficient conditions for posterior consistency. In addition to the
well-known Kullback-Leibler condition on the prior, the true distribution
and most probability measures in the support of the prior are required to
possess moments up to an order which is determined by the order of the
Wasserstein metric. We further investigate convergence rates of the
posterior distributions for which we need stronger moment conditions. The
required tail conditions are sharp in the sense that the posterior
distribution may be inconsistent or contract slowly to the true
distribution without these conditions. We apply the results to density
estimation with a Dirichlet process mixture prior.

Segnalo il seguente seminario online:
SPEAKER: Larry Wasserman, Carnegie Mellon University
TITOLO: Estimating Background Distributions in Particle Physics<https://economiaefinanza.luiss.it/seminar/2020/09/02/estimating-background-…>
DISCUSSANTS: Pierpaolo Brutti e Hugo Lavenant
DATA: giovedì 22 ottobre, ore 17:00
Per accedere al seminario usare questo link <https://luiss.webex.com/luiss/j.php?MTID=mc7aeaa48fd8e2a105eb34f4522a91c48>
ABSTRACT: To test for new events in particle colliders, one needs a good estimate of the background distribution, that is the null distribution. I'll discuss our work on estimating the background distribution for di-Higgs events. Our methods are based on classifiers and optimal transport.This is joint work with Tudor Manole, Patrick Bryant, Mickael Kuusela and John Alison.

Dear colleagues,
I would like to draw your attention to a recently-opened postdoc position at the University of Florence to work with Francesca R. Nardi and me on various metastability and cut-off topics Of course, the precise research directions will depend on the interests of the postdoc. You can find all the relevant details (including a brief summary of the research topics) at the link https://titulus.unifi.it/albo/viewer?view=files%2F003617972-UNFICLE-fbd4028… <https://titulus.unifi.it/albo/viewer?view=files/003617972-UNFICLE-fbd40280-…>, including instructions on how to apply. Please note that the deadline for applying is quite soon on October 23.
Holding a PhD degree (or being close to completion of one) is highly preferred. Previous research experience in the topics above is a plus, but certainly not required.
Please feel free to forward this announcement to anyone who might be interested, and don’t hesitate to contact Francesca and me for further information.

Buongiorno a tutti,
segnaliamo (inoltrando il messaggio in calce) due importanti novita'
nel campo della Statistica Algebrica:
- l'introduzione del codice 62R01 per 'Statistica algebrica' nella
2020 MSC classification
- il primo volume (numerato 11 in riconoscimento del passato della
comunita' di Statistica Algebrica) della rivista Algebraic Statistics
https://msp.org/astat/

============================
Dear friends,
The year 2020 has been very trying for many members of our community,
but we can't fail to acknowledge two very important milestones for the
field of algebraic statistics: that the 2020 MSC classification now
includes 62R01 for 'algebraic statistics', and that a new journal has
been established!
It is with great pleasure that we announce the availability of the
first issue of “Algebraic Statistics (AStat)”:
—> https://msp.org/astat <—
DOI: 10.2140/astat.2020.11-1
The first volume---numbered 11 to honour the past work of this
community---will consist of two issues with a total of 11 papers, 5 of
which are available online now. The second issue is forthcoming soon.
AStat will be free to read until the end of 2021; thereafter, it will
be available through an MSP or Project Euclid subscription. All
papers become freely available 5 years after publication. Our
publisher, MSP, is a nonprofit corporation based in Berkeley, USA.
We see AStat as a primary forum serving the broad community in a
focused way. As an interdisciplinary endeavor, by definition, a
concerted effort will be made for AStat to serve various constituents
interested in and interacting with algebraic statistics. We invite the
community to send their best work in algebraic statistics to be
considered for publication here. This may include contributions which
connect statistical theory, methodology, or application to the world
of algebra, geometry, and combinatorics in ways that may not be
labeled as traditional.
Do enjoy reading the first issue, and we look forward to welcoming
your contributions to AStat.
On behalf of the entire editorial board,
Sonja and Thomas
Managing Editors of Algebraic Statistics

Dear all,
This is an announcement of the: STAR Online Seminars.
The seminar will be held on Friday 16. October from 11:00-12:00. You will
recieve the link for the zoom room by registering for the seminar at the
following link (https://nettskjema.no/a/159180). The lecture will last for
45 minutes + questions.
This week's speaker is Marta Sanz-Sole from University of Barcelona,
with the seminar: Stochastic wave equations with super-linear coefficients.
Abstract: We consider a stochastic wave equation on $R^d , d \in {1, 2, 3}$,
driven by a Gaussian noise in $(t, x)$, white in time. We assume that the
free terms $b$ and $\sigma$ are such that, for $|x| \rightarrow \infty$,
$|\sigma(x)| < \sigma_1 + \sigma_2|x| (\ln_+(|x|))^a , |b(x)| < \theta_1
+ \theta_2|x| (\ln_+(|x|))^{\delta}$ , (1)
where $\theta_2, \sigma_2 > 0, \delta , a > 0$, with $b$ dominating
over $\sigma$. For any fixed time horizon $T > 0$ and with a suitable
constraints on the parameters $a, \delta, \sigma_2$ and $\theta_2$, we prove
existence of a random field solution to the equation and that this solution
is unique, and bounded in time and in space a.s. The research is motivated
by the article [R. Dalang, D. Khoshnevisan, T. Zhang, AoP, 2019] on a
$1-d$ reaction-diffusion equation with coefficients satisfying conditions
similar to (1). We see that the $L^\infty$- method used by these authors can
be successfully implemented in the case of wave equations. This is joint
work with A. Millet (U. Paris 1, Pantheon-Sorbonne).
After the end of the seminar, you are invited to bring a cup of coffee
or tea and have a chat in our ''Coffee in the Stars'' here you will have
the chance to talk and interact with the other persons that attended
the seminar, and have a digital "coffee break".
We are looking forward to see you, online!
