Properties of affine cellular algebras

Christian Lomp (University of Porto)

Motivated by Lusztig's basis of Hecke algebras, Graham and Lehrer introduced cellular algebras in 1996. As a generalisation of Graham and Lehrer’s cellular algebras, affine cellular algebras have been...

Convergence results in the stochastic sine-Gordon model: an algebraic viewpoint

Alberto Bonicelli (Pavia, Italy)

The importance of the sine-Gordon model in 1+1 spacetime dimensions resides in the integrability of the field theory that it describes. A recent result showed how, within the setting of algebraic...

Change point in the preferential attachement model

Ibrahim Kaddouri (Universite Paris Saclay)

Motivated by the problem of detecting a change in the evolution of a
network, we consider the preferential attachment random graph model with
a time-dependent attachment function. Our goal is to...

Information Percolation for reconstruction problems on graphs

Luca Ganassali (Universite Paris Saclay)

We propose a method of proving impossibility results based on applying strong data-processing inequalities to estimate mutual information between sets of variables forming certain Markov random...
