An extension of min/max flow framework
, 2009 In this paper, the min/max flow scheme for image restoration is revised. The novelty consists of the fol- 24 lowing three parts. The first is to analyze the reason of the speckle generation and then to modify the 25 original scheme.

Strolling along gravitational vacua
Journal of High Energy Physics, 2020 We consider General Relativity (GR) on a space-time whose spatial slices are compact manifolds M with non-empty boundary ∂M. We argue that this theory has a non-trivial space of ‘vacua’, consisting of spatial metrics obtained by an action on a reference ...

A space-time geodesic approach for phase fitted variational integrators
, 2016 The use of space-time geodesic approach of classical mechanics is investigated, in order to derive time adaptive high order phase fitted variational integrators. The proposed technique is employed for systems of which the Lagrangian is of separable form.

On Geometric Phase Model in the Theory of Curves With Myller Configuration
Mathematical Methods in the Applied Sciences, EarlyView.ABSTRACT In this paper, we introduce a linearly polarized light wave in an optical fiber and rotation of the polarization plane through the Frenet‐type frame with Myller configuration. Since the geometric evaluation and interpretations of a polarized light wave are associated with geometric phase, a new type of geometric phase model has been ...

Bijections of geodesic lamination space preserving left Hausdorff convergence
, 2018 International audienceWe introduce an asymmetric distance function, which we call the ``left Hausdorff distance function", on the space of geodesic laminations on a closed hyperbolic surface of genus at least 2.

Geodesic Flows in Cosmology [PDF]
, 2008 In this brief note we discuss geodesic flows that correspond to cosmological solutions in higher-dimensional supergravity. On the one hand, we explain that S-brane solutions are in one-to-one correspondence with geodesic curves on the moduli space ...

On geodesic mappings of threesymmetric spaces
Pracì Mìžnarodnogo Geometričnogo CentruThe paper is devoted to the study of properties of pseudo-Riemannian spaces admitting nontrivial geodesic mappings. Necessary and sufficient conditions are found for A-threesymmetric spaces to admit nontrivial geodesic mappings.
