In this paper, we extend the Atiyah--Guillemin--Sternberg convexity theorem and Delzant's classification of symplectic toric manifolds to presymplectic manifolds. We also define and study the...

We present a new family of dualities for three-dimensional gauge theories, motivated by the brane realization of the reduction of four-dimensional dualities on a circle. This family can be...

We study the action of the orthogonal group on the little n-disks operads. As an application we provide small models (over the reals) for the framed little n-disks operads. It follows in...

We prove that for Voronoi percolation on \mathbb{R}^d, there exists p_c\in[0,1] such that
- for p<pc, there exists cp>0 such that \mathbb{P}_p[0\text{...

Theoretical descriptions of observable quantities in cosmological perturbation theory should be independent of coordinate systems. This statement is often referred to as gauge-invariance of...

Genus two partition functions of 2d chiral conformal field theories are given by Siegel modular forms. We compute their conformal blocks and use them to perform the conformal bootstrap. The...

We study correlation functions of a conserved spin-1 current J_\mu in three dimensional Conformal Field Theories (CFTs). We investigate the constraints imposed by permutation symmetry and...

We construct a Hennings type logarithmic invariant for restricted quantum sl(2) at a 2p-th root of unity. This quantum group U is not braided, but factorizable. The invariant is defined for a...

We prove an inequality on decision trees on monotonic measures which generalizes the OSSS inequality on product spaces. As an application, we use this inequality to prove a number of new results...

We describe a large family of nonequilibrium steady states (NESS) corresponding to forced flows over obstacles. The spatial structure at large distances from the obstacle is shown to be...

The modern conformal bootstrap program often employs the method of linear functionals to derive the numerical or analytical bounds on the CFT data. These functionals must have a crucial "...

We investigate the behaviour of the bosonic string on AdS3 with H-flux at stringy scales, looking in particular for a `tensionless` limit in which there are massless higher spin gauge fields. We...
