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)....

Arthur Jacot, Franck Gabriel, Clément Hongler

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...

Alba Grassi, Marcos Marino

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...

Goran Jelic-Cizmek, Francesca Lepori, Julian Adamek, Ruth Durrer

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...

Anton Alekseev, Arkady Berenstein, Benjamin Hoffman, Yanpeng Li

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...

Yi-Ning Hsiao, Andras Szenes

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...

Alexei Oblomkov, Andrei Okounkov, Rahul Pandharipande

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...

Norbert Hungerbühler, Clemens Pohle

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...

Andrea Dei, Matthias R. Gaberdiel, Alessandro Sfondrini

The plane-wave limit of {\rm AdS}_3 \times {\rm S}^3 \times {\rm S}^3 \times {\rm S}^1 is analysed for generic null-geodesics that are not necessarily BPS. For the case of pure NS-NS flux it is...

Alexandre Belin, Alejandra Castro, Joao Gomes, Christoph A. Keller

We discuss the application of Siegel paramodular forms to the counting of polar states in symmetric product orbifold CFTs. We present five special examples and provide exact analytic counting...
