[Seminar] "Resurgence and Exact results in Supersymmetric gauge theories" by Masazumi Honda

Discussion seminar, 2pm in L5EF06 (part of TSVP Thematic Program "Exact Asymptotics: From Fluid Dynamics to Quantum Geometry")

In the past decades, there appeared many exact results in supersymmetric gauge theories thanks to localization method. These exact results are useful to study properties of perturbative series in quantum field theory (QFT) especially in the following two senses. First we can systematically analyze perturbative series around (non-)trivial saddle points in QFT...

[Seminar] "Borel Summability of WKB Solutions for Higher-Order Equations" by Nikita Nikolaev

Discussion seminar, 2pm in L5EF06 (part of TSVP Thematic Program "Exact Asymptotics: From Fluid Dynamics to Quantum Geometry")

Abstract: I will explain in some detail my recent proof of Borel summability of WKB solutions of singularly perturbed higher-order linear ODEs. The proof consists of reducing the problem to a matrix Riccati differential equation in a standard form. Applying the Borel transform, we get a nonlinear PDE which we solve using the method of successive approximations. The biggest challenge is to show that this solution can be analytically continued along a ray in the Borel plane, and this involves keeping track of an interesting Stokes phenomenon.

[Seminar] "Microbe-Machine cybernetic coupling: A feedback loop for ethology and proto intelligences study " by Charles Fosseprez

Profile: Deep into the micro-world, I've been captivated by the complexity of microbial communities. My scientific journey is rooted in the exploration of collective evolution within living systems. Biochemistry, Microbiology and Cybernetics are my focal points, and I'm eager to share the marvels of this field with a broader audience. My approach is decidedly interdisciplinary, with a global footprint spanning diverse subjects. From unraveling the geometric symphony of embryo organization to delving into the fabrication of nanorobots for information processing, my pursuits have been wide-ranging. I've navigated through startups and ventured into the realm of art, guided by a persistent curiosity about constraints and compartments in biological systems. Philosophical contemplation is woven into my scientific exploration, yet I maintain a practical mindset as I am an Engineer with an eye on real-world applications.

EVSP Talk: "Life Is Like a Box of Chocolates: our experience with an alternative model organism" by Daniel Chourrout

Our knowledge of modern biology is based on the study of just a handful of species, which, due to technological investments that have been made, have become increasingly unavoidable. Neglecting, sometimes forgetting, almost all other life forms has been a consequence of this. The problem seems insoluble, but new scientific disciplines fortunately required moving beyond classic laboratory species. One of them is evo-devo, a fairly recent combination of two traditional disciplines, evolutionary biology and developmental biology. Questions on the evolution of animal development led several of us to choose Oikopleura dioica, a species little known to the general public but of considerable importance in marine ecosystems. The first results were a little shocking, but that was not the end of our surprises…
