Motivated by topology, we develop a general theory of traces and shadows in an endobicategory, which is a bicategory C with an endobifunctor \Sigma\colon \mathbf C \to\mathbf C . Applying this...

We introduce an endofunctor D in the category of augmented props with the property that for any representation of a prop P in a vector space V the associated prop DP admits an induced...

We study the impact of the often neglected lensing contribution to galaxy number counts on the E_{g} statistics which is used to constrain deviations from GR. This contribution affects...

We classify the phases of N=2 elliptic models in terms of their global properties i.e. the spectrum of line operators. We show the agreement between the field theory and the M-theory analysis...

Let $\T^m$ be the m-dimensional unit torus, $m\in\N$. The torsional rigidity of an open set $\Omega \subset \T^m$ is the integral with respect to Lebesgue measure over all starting points x∈Ω of...

In this paper, we consider the set of interfaces between + and - spins arising for the critical planar Ising model on a domain with + boundary conditions, and show that it converges towards CLE(...

We study the loop O(n) model on the honeycomb lattice. By means of local non-planar deformations of the lattice, we construct a discrete stress-energy tensor. For n\in [-2,2], it gives a new...

We present a new N-body code, gevolution, for the evolution of large scale structure in the Universe. Our code is based on a weak field expansion of General Relativity and calculates all six...

We present a new computation of the critical value of the random-cluster model with cluster weight q≥1 on Z^{2}. This provides an alternative approach to the result of Beffara and...

The large level limit of the N=2 minimal models that appear in the duality with the N=2 supersymmetric higher spin theory on AdS_3 is shown to be a natural subsector of a certain symmetric...

We count points over a finite field on wild character varieties of Riemann surfaces for singularities with regular semisimple leading term. The new feature in our counting formulas is the...

Given a tropical variety X and two non-negative integers p and q we define homology group H_{p,q}(X). We show that if X is a smooth tropical variety that can be represented as the...
