Elsner, Luca and Tachiya proved in 2019 that the values of the Jacobi-theta
constants θ3(mτ) and θ3(nτ) are algebraically independent
over Q for distinct integers m,n under some conditions on τ.

We extend results of Kass--Wickelgren to define an Euler class for a
non-orientable (or non-relatively orientable) vector bundle on a smooth scheme,
valued in the Grothendieck--Witt group of the ground field. We use a root stack
constructio...

In this article I discuss the Jacobi metric in various contexts such as
momentum constraint, Eisenhart lift, frame dragging effect, and Randers-Finsler
metrics that share a common Jacobi metric. First, I introduce the constraint
with relati...

We report theoretical results for the electronic contribution to thermal and
electrical transport for chiral superconductors belonging to even or odd-parity
E1 and E2 representations of the tetragonal and hexagonal point groups.

We study type-B conformal anomalies associated with 21-BPS
Coulomb-branch operators in 4D N=2 superconformal field theories.
When the vacuum preserves the conformal symmetry these anomalies coincide with
the two-point ...

Let α be a p×q interval matrix with p≥q and with the
endpoints of all its entries in the set of the rational numbers. We prove that,
if α contains a rank-r real matrix with r∈{2,q−2,q−1,q},
then it...

Recent advances in electronics are enabling substantial processing to be
performed at each node (robots, sensors) of a networked system. Local
processing enables data compression and may mitigate measurement noise, but it
is still slower co...

Do you remember your first video game console? We remember ours. Decades ago,
they provided hours of entertainment. Now, we have repurposed them to solve
dynamic and stochastic optimization problems. With deep reinforcement learning
methods...

In this paper we deal with a complex real world scheduling problem closely
related to the well-known Resource-Constrained Project Scheduling Problem
(RCPSP). The problem concerns industrial test laboratories in which a large
number of tests...
