Wandering singularities [PDF]

open access: yesJournal of Differential Geometry, 2021
Parabolic geometric flows are smoothing for short time however, over long time, singularities are typically unavoidable, can be very nasty and may be impossible to classify. The idea of [CM6] and here is that, by bringing in the dynamical properties of the flow, we obtain also smoothing for large time for generic initial conditions. When combined with [

The Sharp Upper Estimate Conjecture for the Dimension δk(V) of New Derivation Lie Algebra

open access: yesMathematics, 2022
Hussain, Yau, and Zuo introduced the Lie algebra Lk(V) from the derivation of the local algebra Mk(V):=On/(g+J1(g)+⋯+Jk(g)). To find the dimension of a newly defined algebra is an important task in order to study its properties.

Avoidance of Singularity during the Gravitational Collapse with String T-Duality Effects

open access: yesUniverse, 2023
In this paper, we explore the gravitational collapse of matter (dust) under the effect of zero-point length l0. During the gravitational collapse, we neglect the backreaction effect of pre-Hawking radiation (in the sense that it is a small effect and ...

Singularities in Static Spherically Symmetric Configurations of General Relativity with Strongly Nonlinear Scalar Fields

open access: yesGalaxies, 2021
There are a number of publications on relativistic objects dealing either with black holes or naked singularities in the center. Here we show that there exist static spherically symmetric solutions of Einstein equations with a strongly nonlinear scalar ...

The de Broglie–Bohm Quantum Theory and Its Application to Quantum Cosmology

open access: yesUniverse, 2021
We review the de Broglie–Bohm quantum theory. It is an alternative description of quantum phenomena in accordance with all the quantum experiments already performed.

Geometrical Properties of the Pseudonull Hypersurfaces in Semi-Euclidean 4-Space

open access: yesMathematics, 2021
In this paper, we focus on some geometrical properties of the partially null slant helices in semi-Euclidean 4-space. By structuring suitable height functions, we obtain the singularity types of the pseudonull hypersurfaces, which are generated by the ...

Singular Continuous Spectrum for Singular Potentials [PDF]

open access: yesCommunications in Mathematical Physics, 2017
We prove that Schr dinger operators with meromorphic potentials $(H_{ , }u)_n=u_{n+1}+u_{n-1}+ \frac{g( +n )}{f( +n )} u_n$ have purely singular continuous spectrum on the set $\{E: L(E)

Singular statistics [PDF]

open access: yesPhysical Review E, 2001
We consider the statistical distribution of zeros of random meromorphic functions whose poles are independent random variables. It is demonstrated that correlation functions of these zeros can be computed analytically and explicit calculations are performed for the 2-point correlation function. This problem naturally appears in e.g.

Mapping the Tilt and Torsion Angles for a 3-SPS-U Parallel Mechanism

open access: yesRobotics, 2023
This article presents the analysis of a parallel mechanism of type 3-SPS-U. The usual singularity approach is carried out with respect to the Euler angles of the universal joint. However, this approach is computationally expensive especially when stacked
