Tubular Surfaces Around Timelike Biharmonic Curves in Lorentzian Heisenberg Group Heis3

open access: yesAnalele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2012
In this paper, we describe a new method for constructing a tubular surface surrounding a timelike biharmonic curve in the Lorentzian Heisenberg group Heis3. Firstly, we characterize timelike biharmonic curves in terms of their curvature and torsion. Also,

Uniqueness of a positive solution for quasilinear elliptic equations in Heisenberg group

open access: yesElectronic Journal of Differential Equations, 2016
In this note we address the question of uniqueness of the Brezis-Oswald problem for the p-Laplacian operator in Heisenberg Group.

A kinematic model of stick‐insect walking

open access: yesPhysiological Reports, 2019
Animal, and insect walking (locomotion) in particular, have attracted much attention from scientists over many years up to now. The investigations included behavioral, electrophysiological experiments, as well as modeling studies.

Some Nonlocal Operators in the First Heisenberg Group

open access: yesFractal and Fractional, 2017
In this paper we construct some nonlocal operators in the Heisenberg group. Specifically, starting from the Grünwald-Letnikov derivative and Marchaud derivative in the Euclidean setting, we revisit those definitions with respect to the one of the ...

Hardy’s inequalities for the twisted convolution with Laguerre functions

open access: yesJournal of Inequalities and Applications, 2017
In this article, two types of Hardy’s inequalities for the twisted convolution with Laguerre functions are studied. The proofs are mainly based on an estimate for the Heisenberg left-invariant vectors of the special Hermite functions deduced by the ...

Non-local elliptic systems on the Heisenberg group

open access: yesElectronic Journal of Differential Equations, 2016
We present Liouville type results for certain systems of nonlinear elliptic equations containing fractional powers of the Laplacian on the Heisenberg group.

Spectral form factor as an OTOC averaged over the Heisenberg group

open access: yesPhysics Letters B, 2019
We prove that in bosonic quantum mechanics the two-point spectral form factor can be obtained as an average of the two-point out-of-time ordered correlation function, with the average taken over the Heisenberg group.
