UPPER BOUNDS FOR THE JOINT DENSITY OF A STABLE PROCESS AND ITS MAXIMUM
Abstract: In this article, we obtain integration by parts formulas for the joint law of a stable process and its maximum. The argument is based on a multi-level representation for the joint law which uses the theory of convex majorants for stable processes and the Chambers-Mallows-Stuck representation for stable random variables. As applications, we obtain regularity results for the joint law and upper bounds for the density and its space derivatives.

One World Probability Seminar Thursday 11th June 2020:
Tomorrow we will have a double talk on "A new point of view on topological
phase transitions“. The first talk will be more introductory and accessible
for a large audience.
------------------------------------------------------------
15.00 CEST: Christophe Garban (Lyon)
16.00 CEST: Avelio Sepúlveda (Lyon)
Abstract:
Topological phase transitions were discovered by Berezinskii-Kosterlitz-
Thouless in the 70's. They describe intriguing phase transitions for
classical
spins systems such as the plane rotator model (or XY model).
Part 1 : General introduction on the topological phase transitions. Without
assuming any a priori background, we will discuss how this phase transition
arises in cases such as :
- the XY model (spins on Z^2 with values in the unit circle)
- the integer-valued Gaussian Free Field
- Abelian Yang-Mills on Z^4
We will also discuss some of the main contributions of Fröhlich and Spencer
to
this theory.
Part 2 : A statistical reconstruction problem.
We will connect topological phase transitions to a statistical
reconstruction
problem concerning the Gaussian Free Field and will show that the
feasibility
of the reconstruction undergoes a KT transition.
The talks will be based mostly on the preprint:

Title:
Random time transformation analysis of Covid19 2020
Speaker:
Isaac Meilijson, Tel Aviv University
Abstract:
The SIR epidemiological equations model new affected and removed cases as
roughly proportional to the current number of infected cases. The present
report adopts an alternative that has been considered in the literature, in
which the number of new affected cases is proportional to the α<1 power of
the number of infected cases. After arguing that α=1 models exponential
growth while α<1 models polynomial or linear growth, a simple method for
parameter estimation in differential equations subject to noise, the
random-time transformation RTT of Bassan, Meilijson, Marcus and Talpaz
1997, will be reviewed and applied to fit α and the other parameters in an
attempt to settle the question as to the nature of Covid19. Joint work with
Nitay Alon.
Tutti gli interessati sono invitati a partecipare.

Title: "Currency Anomalies"
||
|*Abstract *|
|
This paper is the first to study the cross-section of currency anomalies
to explore alternative explanations for their existence. Using real-time
data, currency anomalies are profitable during in-sample and
out-of-sample periods, both before and after transaction costs, but
trading profits decrease substantially after the publication of the
underlying academic research. The decline is greater for anomalies with
larger in-sample profits and lower arbitrage costs, and signal ranks and
performance decay quickly, suggesting that currency anomalies reflect
mispricing rather than compensation for risk or statistical bias.
Mispricing is systematically related to mistakes and changes in
analysts’ currency forecasts. In particular, analysts expect anomaly
payoffs that are too low compared with actual anomaly profits. However,
analysts update their forecasts to incorporate lagged anomaly
information. These results are consistent with a behavioral explanation
for currency anomalies.

Title: Entropic repulsion for the occupation-time field of random
interlacements by disconnection
12 JUNE (Friday) - 15:00 - 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:
The model of random interlacements was introduced in 2007 by A.-S.
Sznitman, motivated by questions about the disconnection of discrete
cylinders or tori by the trace of simple random walk. Since then, it has
gained popularity among probabilists due to its percolative properties and
also because of its connections to the free field. Random interlacements on
transient graphs can be constructed as a Poisson point process of doubly
infinite trajectories. After reviewing this model, we will focus on the
rare event that these trajectories disconnect a macroscopic body from
infinity, in the strongly percolative regime. We will ask the following
question: What is the most efficient way for random interlacements to
enforce such disconnection? In other words, how do the trajectories of
random interlacements look like conditionally on disconnection?
