We study algebraic solutions of the Riccati equation over the field of
rational functions C(t), and over the elliptic function field
C(℘,℘′)....

In this paper we present some results on the variety of divisible
MV-algebras. Any free divisible MV-algebra is an algebra of continuous
piecewise linear functions with rational coefficients. Correspondingly,

Dispersion law for a one-dimensional weakly interacting Bose gas with
zero boundary conditions

Quantum Gases
From the time-dependent Gross equation, we find the quasiparticle dispersion
law for a one-dimensional weakly interacting Bose gas with a non-point
interatomic potential and zero boundary conditions (BCs). The result coincides
with the disp...
Non-Archimedean Analytic Singular Homology Based On Cosimplicial
Perfectoid Spaces and Integration along Cycles

Mathematics
Number Theory
Algebraic Geometry
We introduce singular homology for non-Archimedean analytic spaces using a
cosimplicial perfectoid space as a Galois representation. We define an
integration along a cycle, which gives a pairing with the singular homology and
the space of d...

The geometric and algebraic properties of Gray categories with duals are
investigated by means of a diagrammatic calculus. The diagrams are
three-dimensional stratifications of a cube, with regions, surfaces, lines and
vertices labelled by ...

The eta invariant appears regularly in index theorems but is known to be
directly computable from the spectrum only in certain examples of locally
symmetric spaces of compact type. In this work, we derive some general formulas
useful for ca...

In this article bipartite planar graphs St_r are investigated, r the number
of their plane regions. Bounds for the graded Betti numbers and the projective
dimension of the quotient ring associated to such graphs are discussed. We
prove that...

The proton-magnetic reaction is commonly used in MRI machines with a strong
magnetic field of over 1 T, while this study hypothesized that the electron
magnetic reaction of hydrogen could affect the hydrogen bonds of
double-stranded DNA (ds...

Analysis of PDEs
We consider the geometric inverse problem of determining a closed Riemannian
manifold from measurements of the heat kernel in an open subset of the
manifold. In this paper we analyze the stability of this problem in the class
of n-dimensi...

We introduce a new class of possibly noncompact n-dimensional manifolds
without boundary associated to finite data which we call topological automata.
This class is large enough to contain many interesting examples of open
