Speaker: Professor Anders Björn, Linkoping University and OIST TSVP Visiting Scholar Title: The Dirichlet problem and boundary regularity for nonlinear parabolic equations

Abstract: The p-parabolic equation \[ \partial_t u = \Delta_p u := \dvg(|\nabla u|^{p-2}\nabla u) \] is a nonlinear cousin of the classical heat equation. As such, it offers both difficulties and advantages compared with the heat equation. In the talk, we consider the Perron method for solving the Dirichlet problem for the p-parabolic equation in general bounded domains in $R^{n+1}$. Compared to space-time cylinders, such domains allow the space domain to change in time. Of particular interest will be boundary regularity for such domains, i.e. whether solutions attain their boundary data in a continuous way. Relations between regular boundary points and barriers will be discussed, as well as some peculiar examples and surprising phenomena related to boundary regularity. Towards the end I will discuss the same type of questions for two other nonlinear cousins of the heat equation, the porous medium equation \[ \partial_t u = \dvg(u^m) \] and the so-called normalized p-parabolic equation \[ \partial_t u = |\nabla u|^{2-p}\Delta_p u. \] The talk is based on collaborations with Jana Bj\"orn (Link\"oping), Ugo Gianazza (Pavia), Mikko Parviainen (Jyv\"askyl\"a) and Juhana Siljander (Jyv\"askyl\"a).

Supersymmetry is a remarkable invariance property of physical theories which extends the usual notion of a symmetry algebra to allow for the inclusion of fermionic generators. Field theories with supersymmetry exhibit many physically relevant phenomena such as quark confinement, dynamical symmetry breaking and non-perturbative dualities in a setting where they can be studied precisely using analytic methods. Supersymmetric QFTs have also played a key role in the development of the AdS/CFT correspondence, for which they provide the best understood examples. In this course, Dr. Nick Dorey will give an overview of these developments emphasizing those things which we can calculate exactly.

Abstract:

Collective structural arrangements and cell migration are important physical processes underlying tissue development and regeneration. Understanding the complexity of cell-cell interactions and the emergence of collective behaviors at the tissue scale presents formidable challenges both experimentally and theoretically.

In this talk, I will discuss recent theoretical work on the dynamical patterns that emerge at the tissue scale from localized rearrangements and topological defects. Using a multi-phase field model, we demonstrate that tissue fluidity stems from cell neighbor exchanges, serving as transient sources of vortical flow. This flow emerges from the relative dispersion of cells at a rate proportional to the frequency of rearrangements. Balancing collective migration with relative cell motion appears to be essential for maintaining tissue shape and fluidity. Using a cell-based model, we study the tissue's response to the presence of a vortex. While solid-like behavior tends toward conical shapes, localized fluidization triggers the transition to a tube, which is fundamental in biological tissues.

Talk by Professor Mohsen Razavi (University of Leeds) Seminar Summary: Data security in the quantum era can be one of the key challenges that telecom operators will face in the coming years. With the recent trend in advanced quantum computing machines, the need for implementing alternative solutions for secure communications—those that do not rely on computational complexity assumptions—has become more urgent.
