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?

Subject: 8 PhD positions at GSSI
DEADLINE June,11
Dear Colleagues,
This is to announce the opening for 8 PhD Fellowships in ?Mathematics in Natural, Social and Life Sciences? at Gran Sasso
Science Institute (GSSI) starting in October 2020 - deadline for application: June 11, 2020, info:
https://applications.gssi.it/phd/
The 8 PhD fellowships including "4 years - ? 16.159,91 gross yearly - free accommodation - free luncheon vouchers and
canteen",
are awarded in the area of Mathematics of GSSI (https://www.gssi.it/people/professors/lectures-maths).
Among them 2 fellowships are given within the GrowBot FET - EU project, under the direction of Professor
Pierangelo Marcati. https://growbot.eu/
Interested candidates can apply to both programs by submitting two different applications.
Students and researchers in Mathematics at GSSI are encouraged to interact with other scientific communities. At GSSI,
we believe that the interdisciplinary endeavor is the most effective way to do science and benefit society. Mathematical
models are ubiquitous in physics, engineering, information theory, social and life sciences, as they provide a
formidable framework to describe the time evolution of deterministic, stochastic and complex systems, which is one of
the main goals at GSSI.
Within the PhD program in Mathematics in Natural, Social and Life Sciences a priority has been established on
mathematical modeling, both towards the traditional areas of application, such as Physics or Engineering, and towards
emerging issues in Biology and in the Social Sciences.
GSSI mathematics researchers are interested in tackling many problems with complementary perspectives and methods. The
area of Mathematics is characterized by four large macro-sectors: Applied Partial Differential Equations, Stochastic
Analysis, Numerical methods and Continuum Mechanics modeling. Within these sectors there is a shared interest in
problems related to fluid dynamics, quantum mechanics, statistical mechanics and also its applications to data science.
Important ideas of classical analysis, probability theory, mathematical physics and theoretical physics are used also
for less traditional applications. Numerical linear algebra and numerical optimization help to design new models and
accompanying numerical algorithms for applications in data mining, machine learning and network science. Continuum
mechanics models, computational methods in fluid dynamics are used not only in their traditional field at the boundary
between applied mathematics and theoretical engineering, but also in nonconventional problems like modeling the full
heart function.
