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 Eg 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 Z2. 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 Hp,q(X). We show that if X is a smooth tropical variety that can be represented as the...
