Mathematical flexibility is increasingly recognized as an important construct of interest for both researchers and practitioners in mathematics education. Flexibility…

Incompressible Turbulence with critical regularity – Luigi De Rosa (University of Basel)
Since the celebrated Kolmogorov Theory of Turbulence from 1941 it has been clear that, at first approximation, a good understanding of incompressible turbulence is subject to the study of weak solutions to the Euler equations having critical…
A McKay correspondence in Donaldson-Thomas theory of Calabi-Yau 4-folds – Sergej Monavari (EPFL)
Donaldson-Thomas theory is classically defined for moduli spaces of sheaves over a Calabi-Yau threefold. Thanks to recent foundational work of Cao-Leung, Borisov-Joyce and Oh-Thomas, DT theory has been extended to Calabi-Yau 4-folds. We discuss how,…
Regularization by noise of an averaged version of the Navier-Stokes equations – Theresa Lange (Bielefeld University)
In [T16], the author constructs an averaged version of the deterministic three-dimensional Navier-Stokes equations (3D NSE) which experiences blow-up in finite time. In the last decades, various works have studied suitable perturbations of ill-posed…
The Parabolic Density Problem – Andrea Merlo (Universidad del Pais Vasco)
In this talk, I will present the solution to the density problem in parabolic spaces in codimension 1 for the…
Costruzione di TQFT di dimensione 3 e 4 – François Costantino (Université de Toulouse III)
Comincerò questo seminario ricordando la definizione delle TQFT in dimensione n e alcuni fatti generali (e.g. la definizione degli invarianti…
Projective Absoluteness from Strong Cardinals – Cesare Straffelini (Universitat de Barcelona)
We will give a proof of an unpublished theorem by Hugh Woodin, which states that if there is a proper class of strong cardinals, then by Lévy collapsing the universe we can find a model of ZFC which is projective absolute under set forcing. This,…
Periods of Mixed Hodge Structures associated to algebraic cycles – Souvik Goswami (University of Barcelona)
Given a pair of algebraic cycles which are homologous to zero, and are in complimentary codimensions, R.Hain, S.Bloch, et.al., in the 1990s established a mixed Hodge structure associated to the pair. A period of this mixed Hodge structure is a real…
Caratterizzazione strutturale dell’acqua liquida: un approccio computazionale basato sulla teoria dei grafi (Pisan Young Seminars in Applied and NUmerical Mathematics) – Chiara Faccio (Scuola Normale Superiore)
L’acqua liquida, oltre ad essere fondamentale per la vita sulla Terra, ha da lungo tempo affascinato gli scienziati a causa…
Around the Danzer Problem and the construction of dense forests – Faustin Adiceam (Université Paris-Est Créteil)
A 1965 problem due to Danzer asks whether there exists a set with finite density in Euclidean space (i.e. « not containing too many points ») intersecting any convex body of volume one. A suitable weakening of the volume constraint leads one to the…
