Spectral positivity and Riemannian coverings

Let (M,g) be a complete non-compact Riemannian manifold. We consider operators of the form ∆g + V , where ∆g is the non-negative Laplacian associated with the metric g, and V a locally integrable function. Let ρ : (M̂ , ĝ) → (M,g) be a Riemannian covering, with Laplacian ∆ĝ and potential V̂ = V ◦ ρ. If the operator ∆ + V is non-negative on (M,g), then the operator ∆ĝ + V̂ is non-negative on (M̂, ĝ)...

Liouville and Carathéodory Coverings in Riemannian and Complex Geometry

A Riemannian manifold resp. a complex space X is called Liouville if it carries no nonconstant bounded harmonic resp. holomorphic functions. It is called Carathéodory, or Carathéodory hyperbolic, if bounded harmonic resp. holomorphic functions separate the points of X . The problems which we discuss in this paper arise from the following question: When a Galois covering X with Galois group G ov...

Spectral sharpening with positivity

Spectral sharpening is a method for developing camera or other optical-device sensor functions that are more narrowband than those in hardware, by means of a linear transform of sensor functions. The utility of such a transform is that many computer vision and color-correction algorithms perform better in a sharpened space, and thus such a space can be used as an intermediate representation for...

The Partial Positivity of the Curvature in Riemannian Symmetric Spaces

In this paper, we determine the partial positivity(resp., negativity) of the curvature of all irreducible Riemannian symmetric spaces. From the classifications of abstract root systems and maximal subsystems, we can give the calculations for symmetric spaces both in classical types and in exceptional types.

Noncommutative spectral geometry of Riemannian foliations

According to [9, 8], the initial datum of noncommutative differential geometry is a spectral triple (A,H, D) (see Section 3.1 for the definition), which provides a description of the corresponding geometrical space in terms of spectral data of geometrical operators on this space. The purpose of this paper is to construct spectral triples given by transversally elliptic operators with respect to...
