Surfaces of revolution in the Heisenberg group and the spectral generalization of the Willmore functional
D. A. Berdinskii, I. A. Taimanov Sobolev Institute of Mathematics, Siberian Branch of the Russian Academy of Sciences
Abstract:
We study the generalization of the Willmore functional for surfaces in the three-dimensional Heisenberg group. Its construction is based on the spectral theory of the Dirac operator entering into theWeierstrass representation of surfaces in this group. Using the surfaces of revolution we demonstrate that the generalization resembles the Willmore functional for the surfaces in the Euclidean space in many geometrical aspects. We also observe the relation of these functionals to the isoperimetric problem.
Keywords:
Heisenberg group, surface of revolution, isoperimetric problem, Willmore functional.
