A frequency space for the Heisenberg group [PDF]
Annales de l'Institut Fourier, 2019 We here revisit Fourier analysis on the Heisenberg group H^d. Whereas, according to the standard definition, the Fourier transform of an integrable function f on H^d is a one parameter family of bounded operators on L 2 (R^d), we define (by taking advantage of basic properties of Hermite functions) the Fourier transform f\_H of f to be a uniformly ...

Compensated compactness and the Heisenberg group [PDF]
Mathematische Annalen, 1994 The Jacobian \(\text{Jac}(F)\) of a map \(F\) from the Heisenberg group into itself is shown to map a suitable Sobolev space of the group into the Hardy space \(H^ 1\). From this result and a weak convergence theorem for the space \(H^ 1\) of the Heisenberg group, a compensated compactness property for the Jacobian is obtained.

p-Mechanics and Field Theory [PDF]
, 2004 The orbit method of Kirillov is used to derive the p-mechanical brackets [math-ph/0007030, quant-ph/0212101]. They generate the quantum (Moyal) and classic (Poisson) brackets on respective orbits corresponding to representations of the Heisenberg group ...

Convex functions on the Heisenberg group [PDF]
Calculus of Variations and Partial Differential Equations, 2003 Convexity is certainly a very important property in many fields. To develop an intrinsic theory of fully nonlinear subelliptic equations, the authors of this paper discuss convexities of functions on the Heisenberg group. Group convexity, horizontal convexity and viscosity convexity are considered.

A Romantic Genius? The Experience of Knowledge that Shaped Werner Heisenberg's Scientific Persona. [PDF]
Ber WissIn 1976, the year that Werner Heisenberg passed away, Armin Hermann published a short biography, titled Werner Heisenberg in Selbstzeugnissen und Bilddokumenten. Since then, historians and biographers have offered their accounts on Heisenberg's life and his contributions to modern physics. Many of these biographies present Heisenberg as a genius.

Steiner’s formula in the Heisenberg group [PDF]
Nonlinear Analysis, 2015 Abstract Steiner’s tube formula states that the volume of an ϵ -neighborhood of a smooth regular domain in R n is a polynomial of degree n in the variable ϵ whose coefficients are curvature integrals (also called quermassintegrals). We prove a similar result in the sub-Riemannian setting of the first Heisenberg group. In

Frontiers in Immunology, 2018 Low oxygen tension or hypoxia is a determining factor in the course of many different processes in animals, including when tissue expansion and cellular metabolism result in high oxygen demands that exceed its supply.
