Reidemeister numbers of group automorphisms encode the number of twisted
conjugacy classes of groups and might yield information about self-maps of
spaces related to the given objects. Here we address a question posed by

In this paper, the Cauchy problem for a Friedrichs system on a globally
hyperbolic manifold with a timelike boundary is investigated. By imposing
admissible boundary conditions, the existence and the uniqueness of strong
solutions are shown...
On robust fundamental theorems of asset pricing in discrete time
July 6, 2020

Mathematical Finance
This paper is devoted to a study of robust fundamental theorems of asset
pricing in discrete time and finite horizon settings. Uncertainty is modelled
by a (possibly uncountable) family of price processes on the same probability
space. Our ...
Are chain-complete posets co-wellpowered?

We show that the category of chain-complete posets is co-wellpowered, which
corrects the previous version....

Logic in Computer Science
The paper gives a detailed presentation of a framework, embedded into the
simply typed higher-order logic and aimed at the support of sound and
structured reasoning about various properties of models of imperative programs
with interleaved ...
Existence of at least k solutions to a fractional p-Kirchhoff
problem involving singularity and critical exponent

Mathematics
Analysis of PDEs
We study the existence of nonnegative solutions to the following nonlocal
elliptic problem involving singularity
\begin{align}
\mathfrak{M}\left(\int_{Q}\frac{|u(x)-u(y)|^p}{|x-y|^{N+ps}}dxdy\right)(-\Delta)_{p}^{s}
u&=\frac{\lambda}{|u...
Additivity and Double Coset formulae for the Motivic and \'Etale
Becker-Gottlieb transfer
July 5, 2020

Mathematics
Algebraic Geometry
In this paper, which is a continuation of earlier work by the first author
and Gunnar Carlsson, one of the first results we establish is the additivity of
the motivic Becker-Gottlieb transfer, as well as their \'etale realizations.
This ext...
Motivic and \'Etale Spanier-Whitehead duality and the Becker-Gottlieb
transfer
July 5, 2020

Mathematics
Algebraic Geometry
In this paper, we develop a theory of Becker-Gottlieb transfer based on
Spanier-Whitehead duality that holds in both the motivic and \'etale settings
for smooth quasi-projective varieties in as broad a context as possible: for
example, for ...

We study the graph parameter elimination distance to bounded degree, which
was introduced by Bulian and Dawar in their study of the parameterized
complexity of the graph isomorphism problem. We prove that the problem is
