Recently, Hazeltine-Liu, and independently Haan-Kim-Kwon, proved a local
converse theorem for SO2n​(F) over a p-adic field F, which
says that, up to an outer automorphism of SO2n​(F), an irreducible
generic rep...

We study the scaling of ground state entanglement entropy of various free
fermionic models on one dimensional lattices, where the hopping and pairing
terms decay as a power law. We seek to understand the scaling of entanglement
entropy in g...
A Two-Dimensional String Cosmology

Physics
High Energy Physics - Theory
We study two-dimensional string theory on a time-dependent background, whose
worldsheet description consists of Liouville theory at central charge c = 1 and
Liouville theory at central charge c = 25, together with the conformal ghosts.
We c...
Deep Orthogonal Hypersphere Compression for Anomaly Detection

Many well-known and effective anomaly detection methods assume that a
reasonable decision boundary has a hypersphere shape, which however is
difficult to obtain in practice and is not sufficiently compact, especially
when the data are in hi...

This paper addresses the problem of anticipating the next-active-object
location in the future, for a given egocentric video clip where the contact
might happen, before any action takes place. The problem is considerably hard,
as we aim at ...

The Standard Model Effective Field Theory (SMEFT) provides a robust framework
to interpret experimental measurements in the context of new physics scenarios
while minimising assumptions on the nature of the underlying UV-complete
theory. We...

Doubly robust estimators have gained widespread popularity in various fields
due to their ability to provide unbiased estimates under model
misspecification. However, the asymptotic theory for doubly robust estimators

The MICROSCOPE space mission has tested the weak equivalence principle
finding no violation to about 1e-15, about two orders of magnitude better than
on the ground. We review this result looking for lessons for the future. The
acceleration ...

In this paper we describe an algorithm for computing the left, right, or
2-sided congruences of a finitely presented semigroup or monoid with finitely
many classes, and alternative algorithm when the finitely presented semigroup
or monoid i...
