This study proposes two new dynamic assignment algorithms to match refugees
and asylum seekers to geographic localities within a host country. The first,
currently implemented in a multi-year randomized control trial in Switzerland,
seeks t...

In this paper, we present a Bayesian multilingual document model for learning
language-independent document embeddings. The model is an extension of BaySMM
[Kesiraju et al 2020] to the multilingual scenario. It learns to represent the
docum...
On odd-dimensional modular tensor categories

We study odd-dimensional modular tensor categories and maximally non-self
dual (MNSD) modular tensor categories of low rank. We give lower bounds for the
ranks of modular tensor categories in terms of the rank of the adjoint
subcategory and...

The purpose of this work is to establish a quantitative and constructive
stability result for a class of subcritical Gagliardo-Nirenberg-Sobolev
inequalities which interpolates between the logarithmic Sobolev inequality and
the standard Sob...

We present numerical experiments that test the predictions of a conjecture of
Gaiotto-Moore-Neitzke and Gaiotto concerning the monodromy map for opers, the
nonabelian Hodge correspondence, and the restriction of Hitchin's hyperk\"ahler

Lurie's theorem states that there exists a sheaf of ring spectra on the site
of formally \'etale Deligne--Mumford stacks over the moduli stack of
p-divisible groups of height n, which agrees with the classical Landweber
exact functor th...

We study asymptotic behavior of the moments Mk(λ) of the sum
X1+⋯+XNλ, where Nλ follows the Poisson probability
distribution with mean value λ and {Xj} is a family of i.i.d.

A nonlinear algebraic equation system of 5 variables is numerically solved,
which is derived from the application of the Fourier transform to a

We propose a notion of causal influence that describes the `intrinsic' part
of the contribution of a node on a target node in a DAG. By recursively writing
each node as a function of the upstream noise terms, we separate the intrinsic

In this article, the existence of Ulrich bundles on projective bundles
P(E)→X is discussed. In the case, that the base variety X is a
