Kantorovich-Rubinstein quasi-metrics II: Hyperspaces and powerdomains

چکیده

We show that the Kantorovich-Rubinstein quasi-metrics dKR and dKRa of Part I extend naturally to various spaces previsions, in particular not just linear previsions (roughly, measures) I. There are natural isomorphisms between Hoare Smyth powerdomains, as used denotational semantics, discrete sublinear normalized superlinear respectively. Turning corresponding hyperspaces, namely same but equipped with lower Vietoris upper topologies instead, this turns into homeomorphisms space so-called weak topology. Through these again, two powerdomains inherit dH dQ, respectively, reminiscent well-known Hausdorff metric. Then we an algebraic complete quasi-metric again complete, those quasi-metrics, similarly continuous complete. Furthermore, case, dH-Scott topology coincides topology, dQ-Scott

Imaging with Kantorovich-Rubinstein Discrepancy

We propose the use of the Kantorovich-Rubinstein norm from optimal transport in imaging problems. In particular, we discuss a variational regularisation model endowed with a Kantorovich-Rubinstein discrepancy term and total variation regularization in the context of image denoising and cartoon-texture decomposition. We point out connections of this approach to several other recently proposed me...

The phylogenetic Kantorovich-Rubinstein metric for environmental sequence samples.

It is now common to survey microbial communities by sequencing nucleic acid material extracted in bulk from a given environment. Comparative methods are needed that indicate the extent to which two communities differ given data sets of this type. UniFrac, which gives a somewhat ad hoc phylogenetics-based distance between two communities, is one of the most commonly used tools for these analyses...

Optimal Couplings of Kantorovich-Rubinstein-Wasserstein Lp-distance

The research is supported by Zhejiang Provincial Education Department Research Projects (Y201016421) Abstract We achieve that the optimal solutions according to Kantorovich-Rubinstein-Wasserstein Lp−distance (p > 2) (abbreviation: KRW Lp−distance) in a bounded region of Euclidean plane satisfy a partial differential equation. We can also obtain the similar results about Monge-Kantorovich proble...

Warped product and quasi-Einstein metrics

Warped products provide a rich class of physically significant geometric objects. Warped product construction is an important method to produce a new metric with a base manifold and a fibre. We construct compact base manifolds with a positive scalar curvature which do not admit any non-trivial quasi-Einstein warped product, and non compact complete base manifolds which do not admit any non-triv...
