The detection of interesting patterns in large high-dimensional datasets is
difficult because of their dimensionality and pattern complexity. Therefore,
analysts require automated support for the extraction of relevant patterns. In
this pap...

History and Overview
Mathematicians have traditionally been a select group of academics that
produce high-impact ideas allowing substantial results in several fields of
science. Throughout the past 35 years, undergraduates enrolling in mathematics
or statistics...

Probabilistic models are often trained by maximum likelihood, which
corresponds to minimizing a specific f-divergence between the model and data
distribution. In light of recent successes in training Generative Adversarial
Networks, alterna...

We consider a novel stochastic multi-armed bandit setting, where playing an
arm makes it unavailable for a fixed number of time slots thereafter. This
models situations where reusing an arm too often is undesirable (e.g. making
the same pro...

This paper gives the first description of derived monodromy on the stringy
K\"ahler moduli space (SKMS) for a general irreducible flopping curve C in a
3-fold X with mild singularities. We do this by constructing two new infinite
helices: t...
Rigid analytic reconstruction of Hyodo--Kato theory

Mathematics
Number Theory
We give a new and very intuitive construction of Hyodo--Kato cohomology and
the Hyodo--Kato map, based on logarithmic rigid cohomology. We show that it is
independent of the choice of a uniformiser and study its dependence on the
choice of ...
Ribbonness of a stable-ribbon surface-link, II. General case
July 23, 2019
Mathematics
Geometric Topology
It is shown that any handle-irreducible summand of every stable-ribbon
surface-link is a unique ribbon surface-link up to equivalences. This is a
generalization of a previously observed result for a stably trivial
surface-link. Two applicat...
Inductive dimensions of coarse proximity spaces

General Topology
In this paper, we generalize Dranishnikov's asymptotic inductive dimension to
the setting of coarse proximity spaces. We show that in this more general
context, the asymptotic inductive dimension of a coarse proximity space is
bigger or equ...

Analyses of upcoming galaxy surveys will require careful modelling of
relevant observables such as the power spectrum of galaxy counts in harmonic
space Cℓ(z,z′). We investigate the impact of disregarding relevant
relativistic effects...

We study a method for proportional representation that was proposed at the
turn from the nineteenth to the twentieth century by Gustav Enestr\"om and
Edvard Phragm\'en. Like Phragm\'en's better-known iterative minimax method, it
is assumed ...
