  • Johanna Bimmermann :From Magnetically Twisted to Hyperkähler 

    The tangent bundle of a Kähler manifold admits in a neighborhood of the zero section a hyperkähler structure. From a symplectic point of view, this means we have three symplectic...

Manin's Conjecture For Spherical Fano Threefolds
4:30pm|Simonyi 101 and Remote Access

When an algebraic variety over the rational numbers contains infinitely many rational points, we may study their distribution. In particular, for Fano varieties, the asymptotic behavior of the number of rational points of bounded height is predicted...

Computer Science/Discrete Mathematics Seminar II

Online Discrepancy Minimization
10:30am|Simonyi Hall 101 and Remote Access

The online discrepancy minimization problem asks, given unit vectors v_1, ..., v_t arriving one at a time, for online signs x_1 ..., x_t4 in {-1, 1} so that the signed sum x_1 v_1 + ... + x_t v_t has small coordinates in absolute value. 

In the first...

Tangent Bundles in p-adic Geometry
3:30pm|Simonyi Hall 101 and Remote Access

Because of the existence of approximate p-power roots, a perfectoid algebra over Q_p admits no continuous derivations, and thus the natural Kahler tangent space of a perfectoid space over Q_p is identically zero. However, it turns out that many...

Marton's Conjecture, aka the Polynomial Freiman--Ruzsa Conjecture
Frederick Manners
11:00am|Simonyi 101 and Remote Access

A function $f : \mathbb{F}_2^n \to \mathbb{F}_2^n$ is linear if $f(x+y)=f(x)+f(y)$ for all pairs $(x,y)$.

Suppose $f$ is "a bit linear" -- say, $f(x+y)=f(x)+f(y)$ for 1% of pairs $(x,y)$.  Must $f$ agree with a truly linear function a positive...

Cabling Families of Legendrian Embeddings
Eduardo Fernández
9:15am|Remote Access

I will discuss a recursive formula for the homotopy type of the space of Legendrian embeddings of sufficiently positive cables with the maximal Thurston-Bennequin invariant. Via this formula, we identify infinitely many new components within the...

  • Francesco Morabito:Hofer Norms on Braid Groups and Quantitative Heegaard-Floer Homology

    Given a lagrangian link with k components it is possible to define an associated Hofer norm on the braid group with k strands. In this talk we are going to...

Equivariant Floer Homotopy via Morse-Bott Theory
Yusuf Barış Kartal
9:15am|Remote Access

Floer homotopy type refines the Floer homology by associating a (stable) homotopy type to an Hamiltonian, whose homology gives the Hamiltonian Floer homology. In particular, one expects the existing structures on the latter to lift as well, such as...
