We study the impact on the galaxy correlation function of the presence of a vector component in the tracers' peculiar velocities, in the case in which statistical isotropy is violated. We...

We present a public version of the code COFFE (COrrelation Function Full-sky Estimator) available at this https URL The code computes the galaxy two-point correlation function and its multipoles...

This paper revisits the controversy concerning whether gravitational lensing effects make a significant difference to estimation of distance to the Cosmic Microwave Background last scattering...

We study universal spatial features of certain non-equilibrium steady states corresponding to flows of strongly correlated fluids over obstacles. This allows us to predict universal spatial...

In this paper, we prove that Bernoulli percolation on bounded degree graphs with isoperimetric dimension d>4 undergoes a non-trivial phase transition (in the sense that pc<1)....

At initialization, artificial neural networks (ANNs) are equivalent to Gaussian processes in the infinite-width limit, thus connecting them to kernel methods. We prove that the evolution of an...

The conventional Hamiltonian H= p^2+ V_N(x), where the potential V_N(x) is a polynomial of degree N, has been studied intensively since the birth of Quantum Mechanics. In some cases, its...

It is well known that galaxies rotate and their angular momenta are correlated over relatively large scales. However, in a perfect fluid vorticity in conserved and cannot be generated. The...

Let G be a connected semisimple Lie group. There are two natural duality constructions that assign to it the Langlands dual group G and the Poisson-Lie dual group G. The...

The study of the stratification associated to the number of generators of the ideals in the punctual Hilbert scheme of points on the affine plain goes back to the '70s. In this paper, we present...

We propose an explicit formula for the GW/PT descendent correspondence in the stationary case for nonsingular projective 3-folds. The formula, written in terms of vertex operators, is found by...

Suppose there are n harmonic pencils of lines given in the plane. We are interested in the question whether certain triples of these lines are concurrent or if triples of intersection points of...
