The original Leray’s problem concerns the well-posedness of weak solutions to the steady incompressible Navier-Stokes equations in a distorted pipe, which approach to the Poiseuille flow subject to the no-slip boundary condition at spacial infinity.…

BPS invariant from p-adic integrals – Francesca Carocci (Université de Genève)
We consider moduli spaces of one-dimensional semistable sheaves on del Pezzo and K3 surfaces supported on ample curve classes. Working over a non-archimedean local field $F$, we define a natural measure on the $F$-points of such moduli spaces. We…
An exotic structure on a non-orientable 4-manifold via Gluck twisting – Valentina Bais (SISSA)
In this talk I will talk about a joint work with Rafael Torres, in which we create an exotic smooth…
Sobolev-Malliavin regularity of the nodal volume – Michele Stecconi (University of Luxembourg)
Consider the nodal volume of a non-degenerate (in a sense to specify) Gaussian random field defined on a compact Riemannian manifold of dimension d greater or equal to 2. We prove that the law of such random variable has an absolutely continuous…
Unraveling the Interplay of Algebraic and Analytic Restrictions in Fine Pattern Formation – Adolfo Arroyo-Rabasa (UCLouvain)
Fine patterns, such as oscillations and concentrations of mass, are ubiquitous in nature, from the microstructure of materials to the…
Vertex algebras from divisors on Calabi-Yau threefolds – Dylan Butson (University of Oxford)
We will explain two conjecturally equivalent constructions of vertex algebras associated to divisors $S$ on certain toric Calabi-Yau threefolds $Y$. One construction is algebraic, as the kernel of screening operators on lattice vertex algebras…
A Bayesian approach for modelling RNA velocity – Elena Sabbioni (Politecnico di Torino)
RNA velocity is a biological quantity involved in the interpretation of cellular differentiation, exploiting the evolution of gene expression of…
The motivic Satake equivalence – Jakob Scholbach (Padova)
The geometric Satake equivalence, due to Mirkovic and Vilonen, establishes an equivalence between certain perverse sheaves on the affine Grassmannian $Gr_G$, for a split reductive group $G$, and representations of the Langlands dual group $\hat G$.…
A cooking class on exotic surfaces in 4-manifolds – Oliviero Malech (SISSA)
Two smoothly embedded surfaces in the same smooth 4-manifold are called exotic if they are C^0 ambient isotopic without being…
Log intersection theory – Leo Herr (Leiden)
Log structures are “magic powder” that make mildly singular spaces appear smooth. Log schemes literally lie between ordinary schemes and tropical geometry, and are related to Berkovich Spaces. Problems in Gromov-Witten Theory demand intersection…
