On a moment problem of analytic functionals of polynomial hypergroups

Related to radial functions on free groups, we focus on certain polynomial
hypergroups and work out spectral analysis with the help of the Stieltjes
transform of their analytic functionals....

We show that for an arbitrary totally complex number field L the
(regularized) critical L-values of algebraic Hecke characters of L divided
by certain periods are algebraic integers. This relies on a new construction of
an equivariant...

In this work we define a numerical invariant called F-volume. This number
extends the definition of F-threshold of a pair of ideals I and J,
cJ(I) to a sequence of ideals J, I1,…,It. We obtain several
properties that...

The architectures of deep neural networks (DNN) rely heavily on the
underlying grid structure of variables, for instance, the lattice of pixels in
an image. For general high dimensional data with variables not associated with
a grid, the mu...

The search for new physics at high energy accelerators has been at the
crossroads with very little hint of signals suggesting otherwise. The
challenges at a hadronic machine such as the LHC is compounded by the fact that
final states are sw...

Given a right LCM semigroup S and a homomorphism N:S→[1,+∞),
we use the groupoid approach to study the KMSβ-states on C∗(S) with
respect to the dynamics induced by N. We establish necessary and sufficient
condit...

We consider the problem of maximising expected utility from terminal wealth
in a semimartingale setting, where the semimartingale is written as a sum of a
time-changed Brownian motion and a finite variation process. To solve this
problem, w...

Asymptotically flat spacetimes admit both supertranslations and Lorentz

Exactly Solvable and Integrable Systems
In 1983 Bogoyavlenski conjectured that if the Euler equations on a Lie
algebra g0 are integrable, then their certain extensions to
semisimple lie algebras g related to the filtrations of Lie
algebras $\mathfrak g_0\...
