Minimal Surfaces in the Heisenberg Group [PDF]

open access: greenGeometriae Dedicata, 2004
We investigate the minimal surface problem in the three dimensional Heisenberg group, H, equipped with its standard Carnot-Caratheodory metric. Using a particular surface measure, we characterize minimal surfaces in terms of a sub-elliptic partial differential equation and prove an existence result for the Plateau problem in this setting.

The braided Heisenberg group [PDF]

open access: yesJournal of Mathematical Physics, 1993
The braided groups and braided matrices B(R) for the solution R of the Yang–Baxter equation associated to the quantum Heisenberg group are computed. It is also shown that a particular extension of the quantum Heisenberg group is dual to the Heisenberg universal enveloping algebra Uq(h), and this result is used to derive an action of Uq(h) on the ...

Deformations of the discrete Heisenberg group [PDF]

open access: yesProceedings of the Japan Academy, Series A, Mathematical Sciences, 2013
We study deformations of the discrete Heisenberg group acting properly discontinuously on the Heisenberg group from the left and right and obtain a complete description of the deformation space.

Hölder Continuity and Boundedness Estimates for Nonlinear Fractional Equations in the Heisenberg Group [PDF]

open access: yesJournal of Geometric Analysis, 2022
We extend the celebrate De Giorgi-Nash-Moser theory to a wide class of nonlinear equations driven by nonlocal, possibly degenerate, integro-differential operators, whose model is the fractional p -Laplacian operator on the Heisenberg-Weyl group $$\mathbb

On the dimension of Kakeya sets in the first Heisenberg group [PDF]

open access: yes, 2021
We define Kakeya sets in the Heisenberg group and show that the Heisenberg Hausdorff dimension of Kakeya sets in the first Heisenberg group is at least 3.

On the critical Choquard-Kirchhoff problem on the Heisenberg group

open access: yesAdvances in Nonlinear Analysis, 2022
In this paper, we deal with the following critical Choquard-Kirchhoff problem on the Heisenberg group of the form: M ( ‖ u ‖ 2 ) ( − Δ H u + V ( ξ ) u ) = ∫ H N ∣ u ( η ) ∣ Q λ ∗ ∣ η − 1 ξ ∣ λ d η ∣ u ∣ Q λ ∗ − 2 u + μ f ( ξ , u ) , M\left(\Vert u{\Vert }

Campana points on biequivariant compactifications of the Heisenberg group [PDF]

open access: yesEuropean Journal of Mathematics, 2020
We study Campana points on biequivariant compactifications of the Heisenberg group and confirm the log Manin conjecture introduced by Pieropan, Smeets, Tanimoto and Várilly-Alvarado.

Generation of spin-polarized hot electrons at topological insulators surfaces by scattering from collective charge excitations

open access: yesCommunications Physics, 2021
A key feature of topological insulators, such as Bi2Se3 is their protected electronic surface states where the direction of spin is locked to their momentum.
