Given a symplectic 4-manifold it may admit multiple toric
fibrations. These can be seen as boundary points of the moduli
space of almost toric fibrations. We will sketch that all toric
fibrations are in the same connected component of this
moduli...
I'll introduce the genus zero open Gromov-Witten invariants for
even-dimensional Lagrangians. The definition relies on a canonical
family of bounding cochains satisfying the point-like condition of
Solomon-Tukachinsky, with non-commutative...
A translation surface is a closed surface that is obtained by
gluing edges of a polygon in parallel. The group GL2(R) acts on the
collection translation surfaces of a fixed genus g. For a fixed
translation surface S and t greater than 0, we obtain a...
Cryptographic primitives have been used for various
non-cryptographic objectives, such as eliminating or reducing
randomness and interaction. We show how to use cryptography to
improve the time complexity of solving computational
problems...
The All-Pairs Min-Cut problem (APMC) asks to compute the minimum
cut (or equivalently, the maximum flow) between all pairs of nodes
in a graph.1 The naive solution of making n^2 calls to a
single-pair min-cut algorithm was surpassed in 1961 by a...
Helicity is an invariant of divergence free vector fields on a
three-manifold. One of its fundamental properties is invariance
under volume preserving diffeomorphisms. Arnold, having derived an
ergodic interpretation of helicity as an asymptotic...
Conformal field theories in 3D are central to condensed-matter
and high-energy physics. Among them, critical gauge theories,
especially Chern-Simons-matter theories, stand out: They describe
transitions where one or both phases are topologically...
I will begin by motivating the study of invariant distances on
spaces of Legendrians. I will then discuss two main results:
(a) the construction of a new unbounded invariant distance on the
universal cover of many Legendrian isotopy classes ;
(b) the...
We construct the tame part of a split anticyclotomic Euler
system in a setting where local multiplicity one does not hold.
Instead of the traditional zeta integral approach, we prove the
existence of the necessary test vectors using a new method...
In many groups, the optimal diameter for the solutions of the
isoperimetric problem is asymptotically equivalent to the lower
bound coming from their cardinality; in this situation one says
that the Følner function is lossless with respect to the...
