Thanks to the magic (and obvious) relation between the 2n + 1-dimensional Heisenberg group and its vector group [R.
Understanding the nature of these kind of partial differential operators and their invariance on the Heisenberg group requires the admission of solutions.
In this paper we describe a method to derive a Weierstrass-type representation formula for simply connected immersed minimal surfaces in Heisenberg group

Hans-Jurgen Eisler, who heads the DFG Heisenberg group
at the Light Technology Institute.
Ten chapters discuss the skew field of quaternions; elements of the geometry of S3, Hopf bundles, and spin representations; internal variables of singularity free vector fields in a Euclidean space; isomorphism classes, Chern classes, and homotopy classes of singularity free vector fields in 3-space; Heisenberg algebras, Heisenberg groups
, Minkowski metrics, Jordan algebras, and special linear groups; the Heisenbreg group and natural C*-algebras of a vector field in 3-space; the Schrodinger representation and the metaplectic representation; the Heisenberg group
as a basic geometric background of signal analysis and geometric optics; quantization of quadratic polynomials; and field theoretic Weyl quantization of a vector field in 3-space.
This Heisenberg group
has many important applications on Sub-Riemannian geometry and has very important role in physics.
Specific topics include Hormander operators and non-holonomic geometry, Weyl transforms and the inverse of the sub-Laplacian on the Heisenberg group
, corner operators and applications to elliptic complexes, semilinear pseudo-differential equations and traveling waves, trace ideals for Fourier integral operators with non-smooth symbols, the S-transform and why to use it, inversion formulas for two-dimensional Stockwell transforms, Shannon-type sampling theorems on the Heisenberg group
, and a unified point of view on time-frequency representatives and pseudo-differential operators.
