Title: 2-scale convergence for random walks in random environment and
applications to homogenization, hydrodynamics and resistor networks
Abstract: The 2-scale convergence method was introduced by Nguetseng and
Allaire in homogenization theory of partial differential equations and
afterwards successfully adapted to stochastic homogenization, allowing to
deal also with singular structures (see [Jikov&Piatnitski]). We focus here
on 2-scale convergence for random walks.
In the first talk we aim to provide a gentle introduction to 2-scale
convergence for random walks in a random environment with symmetric rates.
Using the Palm theory of random measures we discuss ergodicity issues at a
2-scale level. We then introduce a basic difference calculus and define
2-scale convergence of functions and gradients, corresponding to an
enforced averaging property. Finally we discuss the fundamental compactness
and structure theorem for bounded families of H^1-functions, where
geometrical issues of square integrable forms and the homogenized matrix
emerge.
In the second talk we discuss some applications of the above 2-scale
convergence for random walks in a random environment. A first one is given
by the invariance principle of random walks on the supercritical
percolation cluster of P. Mathieu and A. Piatnitski. We then discuss more
in detail applications to the homogenization of the massive Poisson
equation associated with the random walk, which also enters in the
derivation of the hydrodynamic limit of exclusion and zero range processes.
Finally, we discuss applications to random resistor networks, in particular
to the conductance model and the Miller-Abrahams one associated to Mott
variable range hopping in amorphous solids.

There are many postdoctoral positions available in Montreal for the coming
academic year (at least 13). Further information below; I would be grateful
if you could for circulate this message to anyone you believe may be
interested in applying.
These are for candidates in all areas of mathematics, but I am particularly
interested in encouraging candidates in probability theory and related
fields, to work with members of the probability lab
<http://problab.ca/yul/en/>. Candidates are encouraged to contact lab
members who they are interested in working with, as applications are more
likely to be successful when they have lab support.
Please note that the application deadlines are quite soon - November 13;
candidates are encouraged to submit applications as soon as possible.
There are two postdoctoral fellowship competitions. Further details on the
two programs can be found on MathJobs (
https://www.mathjobs.org/jobs/list/16367 and
https://www.mathjobs.org/jobs/list/16288 - English follows French in the
second posting), and on the probability lab website linked above.
In addition to the vibrant mathematical life in the probability laboratory
and in Montreal more generally, candidates may be interested in the
thematic program on probability and PDEs (link <http://problab.ca/ppde/>),
which will take place in Montreal in the first half of 2022 (postponed from
2021 due to COVID), and featuring several workshops, mini-courses, and
numerous long-term visitors from around the world.
Sincerely,
Louigi.

Dear Alessandra,
We would be grateful if you forward this information to any candidates
who may be interested.
The probability group at UBC plans to hire a postdoctoral fellow
starting in the summer of 2021. This is a 3-year positions with a
relatively low teaching load. Applicants should have obtained a recent
(normally no earlier than 2018) Ph.D. in Mathematics or a closely
related discipline, or expect to complete one before the starting date.
Candidates should demonstrate excellent potential in research and teaching.
Review of applications will begin after November 15, 2020, although
applications received after this date may still be considered.
Application is through mathjobs. The ad and full details may be seen at
https://www.mathjobs.org/jobs/list/16220
We especially welcome applications from women, visible minorities of
other groups under-represented in mathematics.
Please let me know if a different email address should be used.
Please contact any of us for additional information:

Title: Some exponents governing the geometry of planar last passage
percolation and the directed landscape
Abstract: Planar last passage percolation models are canonical examples of
stochastic growth in the Kardar-Parisi-Zhang universality class, where one
considers oriented paths between points in a random environment accruing
the integral of the noise along itself as its weight. Given the endpoints,
the extremal path with the maximum weight is termed as the geodesic.
As the endpoints are allowed to vary in space and time (one dimension for
each), the joint ensemble of the weights gives rise to a four parameter
space-time random energy field, whose conjectural universal weak limit, the
Directed landscape, was recently constructed in a breakthrough work of
Dauvergne, Ortmann and Virag. We shall discuss a few recent results
identifying exponents that govern the space time geometry of this
fundamental object and its prelimits.
In the first talk we shall study the aging behavior at short and large
scales establishing exponents dictating the decay of correlations of
weights in time, in last passage percolation on the lattice with
exponential weights. We shall describe two results corresponding to the
droplet and flat initial conditions confirming conjectures made by Ferrari
and Spohn a few years ago.
In the second talk we shall describe results on fractal geometry
specializing to a Brownian model. In particular, we study the coupling
structure of the geodesic weight profiles at a fixed time (say 1) started
at distinct points at time 0 by analyzing their difference function. Though
in expectation this grows linearly, we show that the difference profile
induces a random measure whose support is fractal and compute its
dimension. We also relate the support of this measure to the exceptional
set of points admitting disjoint geodesics.
Beyond geometric and probabilistic arguments involving geodesic behavior,
the key inputs used are one point fluctuation information, locally
Brownian nature of the geodesic weight profile, and sharp estimates on
rarity of disjoint geodesics, the latter two being consequences of an
invariance property under resampling termed as the Brownian Gibbs property.
These talks are based on a number of works jointly with subsets of Erik
Bates, Alan Hammond, and Lingfu Zhang.

Title: Critical and near-critical scaling limits for the planar Ising model
06 NOVEMBER (Friday) - 14:00 - zoom link: TBA (available on the webpage
https://www.math.unipd.it/~bianchi/seminari/ )
Abstract:
The Ising model, proposed by Lenz in 1920 to describe ferromagnetism, is
one the most studied models of statistical mechanics. Its two dimensional
version has played a special role in rigorous statistical mechanics since
Peierls’ proof of a phase transition in 1936 and Onsager’s derivation of
the free energy in 1944. This continues to be the case today, thanks to new
results on the continuum scaling limit. In this talk, I will first
introduce the model and give a brief historical overview of some milestones
in its analysis. I will then present recent results on its critical and
near-critical scaling limits, focusing on the scaling behavior of the
magnetization. In particular, I will discuss non-central limit theorems for
the magnetization, the emergence of conformal invariance at the critical
point, and exponential decay of correlations in the near-critical regime.

Newman.)
