ON THE QUADRATIC HEISENBERG GROUP

Infinite Dimensional Analysis, Quantum Probability and Related Topics, 2010
In this paper we introduce the quadratic Weyl operators canonically associated to the one mode renormalized square of white noise (RSWN) algebra as unitary operator acting on the one mode interacting Fock space {Γ, {ωn, n ∈ ℕ}, Φ} where {ωn, n ∈ ℕ} is the principal Jacobi sequence of the nonstandard (i.e. neither Gaussian nor Poisson) Meixner classes.

The Heisenberg Group

2014
In this chapter we prove the Stone-von Neumann Theorem, which gives a full characterization of the unitary dual of the Heisenberg group \({\cal H}\). We then apply the trace formula to describe the spectral decomposition of \({L^2}(\Lambda \backslash H)\), where π is the standard integer lattice in \({\cal H}\).

Optimization in the Heisenberg group

Optimization, 2006
In this article, the local unconstrained and the constrained optimization problems in the Heisenberg group are investigated. The framework on which we work is given by the class of weakly H-convex functions recently introduced in the literature. This geometric notion of convexity, that is strictly related to the stratified structure of the group and ...

The Heisenberg Group

2015
This chapter is meant to give a brief and by no means complete description of the Heisenberg group \(\mathbb {H}\), that will be the setting of this work. Customarily this group is presented as a particular group on \(\mathbb {R}^3\). This is not restrictive and to explain why we recall some definitions and basic properties of Carnot groups in order to

Theta and Heisenberg Groups

1992
For the introductory remarks of this chapter let us assume that L is a very ample line bundle on an abelian variety X = V/Λ and φ L : X ↪ ℙ N the associated embedding. Recall the group K(L) consisting of all x ∈ X with t x * L≃L. We will see that the translations of X by elements of K(L) extend to linear automorphisms of ℙ N .

The Heisenberg Group

2017
One of the big contributions of E. M. Stein is the development of harmonic analysis on the Heisenberg group. In a fundamental joint paper with G. B. Folland, Stein laid all the groundwork for this study. In this chapter we reproduce and develop some of that groundwork.
