Abstract

We introduce the so-called extended Lagrangian symbols, and we prove that the C ∗ -algebra generated by Toeplitz operators with these kind of symbols acting on the homogeneously poly-Fock space of the complex space ℂ n is isomorphic and isometric to the C ∗ -algebra of matrix-valued functions on a certain compactification of ℝ n obtained by adding a sphere at the infinity; moreover, the matrix values at the infinity points are equal to some scalar multiples of the identity matrix.

  • Let m ∈ N, the one-dimensional m poly-Fock space F2mðCÞ ⊂ L2ðC, dμÞ consists of all m-analytic functions φ which satisfy ∂ m ∂z φ = ∂ ∂x + i∂ m ∂y φ ð1Þ where dμ = π−1e−z·z dxdy is the Gaussian measure in C and d xdy is the Euclidian measure in R2 = C

  • In [4], the authors studied Toeplitz operators acting on the one-dimensional polyFock space with horizontal symbols such that the limit values at x = ∞ and x = −∞ exist

  • The main result of this paper is the following: the C∗-algebra generated by Toeplitz operators with extended Lagrangian symbols acting on the homogeneously poly-Fock space over Cn is isomorphic and isometric to the C∗-algebra of matrix-valued functions on a certain compactification of Rn with the sphere at the infinity; the values at the infinity points are scalar multiplies of the identity matrix

Summary

Introduction

Let m ∈ N, the one-dimensional m poly-Fock space F2mðCÞ ⊂ L2ðC, dμÞ consists of all m-analytic functions φ which satisfy. In [4], the authors studied Toeplitz operators acting on the one-dimensional polyFock space with horizontal symbols such that the limit values at x = ∞ and x = −∞ exist They proved that the C∗-algebra generated with this class of symbols is isomorphic to the C∗-algebra of functions on R with values on the m × m matrices, whose limit value at x = ∞ and x = −∞ are equal to some scalar multiples of the identity matrix. The main result of this paper is the following: the C∗-algebra generated by Toeplitz operators with extended Lagrangian symbols acting on the homogeneously poly-Fock space over Cn is isomorphic and isometric to the C∗-algebra of matrix-valued functions on a certain compactification of Rn with the sphere at the infinity; the values at the infinity points are scalar multiplies of the identity matrix.
