We study here the crepant resolution correspondence for the torus equivariant descendent Gromov-Witten theories of Hilb(C2) and Sym(C2).The descendent correspondence is obtained from our...

In this paper, we study lensing of 21cm intensity mapping (IM). Like in the cosmic microwave background (CMB), there is no first order lensing in intensity mapping. The first effects in the...

The present text summarizes several factors considered as essential for teacher education according to the state of current research and best practice, with a focus on science teacher education...

Vittorio Tansella, Camille Bonvin, Giulia Cusin, Ruth Durrer, Martin Kunz, Ignacy Sawicki

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...

Vittorio Tansella, Goran Jelic-Cizmek, Camille Bonvin, Ruth Durrer

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...

Igor Novak, Julian Sonner, Benjamin Withers

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...

Hugo Duminil-Copin, Subhajit Goswami, Aran Raoufi, Franco Severo, Ariel Yadin

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...

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...
