The multi-armed bandit (MAB) problem is a widely studied model in the field
of operations research for sequential decision making and reinforcement
learning. This paper mainly considers the classical MAB model with the
heavy-tailed reward d...

General Relativity and Quantum Cosmology
A family of spherically O(d0+1)-symmetric solutions in the model with
m-component anisotropic fluid is obtained. The metrics are defined on a
manifold which contains a product of n−1 Ricci-flat ``internal'' spaces. The
equation of ...

The two only species of isolatable, smallest, or unit charges +e and -e
present in nature interact with the universal vacuum in a polarisable
dielectric representation through two uniquely defined vacuum potential
functions. All of the non-...

Let S be a hyperbolic oriented Riemann surface of finite type. The main
purpose of this paper is to show that non-trivial geometric intersection
between closed curves on S is detected by some symplectic submodules they
naturally determi...

In this paper, we propose a key idea and innovation on the Collatz problem.
Let an odd Collatz's Sequence be Sc(m,t)={n0(m,t),n1(m,t),n2(m,t),…,nm(m,t),nm+1(m,t)} produced by a function $n_{i+1}(m,t)=(3n_{i}(m...

We prove that the smallest degree of an apolar 0-dimensional scheme of a
general cubic form in n+1 variables is at most 2n+2, when n≥8, and
therefore smaller than the rank of the form. For the general reducible cubic
form the smal...

In this work we show that the convergence rate of Orthomin(k) applied to
systems of the form (I+ρU)x=b, where U is a unitary operator and
0<ρ<1, is less than or equal to ρ. Moreover, we give examples of
operators U ...
