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

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.
