Geodesic scattering on hyperboloids and Knörrer’s map [PDF]
Nonlinearity, 2021 Abstract We use the results of Moser and Knörrer on relations between geodesics on quadrics and solutions of the classical Neumann system to describe explicitly the geodesic scattering on hyperboloids. We explain the relation of Knörrer’s reparametrisation with projectively equivalent metrics on quadrics introduced by Tabachnikov and ...

Geodesic Warps by Conformal Mappings [PDF]
International Journal of Computer Vision, 2012 In recent years there has been considerable interest in methods for diffeomorphic warping of images, with applications e.g.\ in medical imaging and evolutionary biology. The original work generally cited is that of the evolutionary biologist D'Arcy Wentworth Thompson, who demonstrated warps to deform images of one species into another.

Conformally Fedosov manifolds and geodesic mappings [PDF]
AIP Conference Proceedings, 2021 We introduce the notion of a conformally Fedosov structure and geodesic mappings of manifolds with affine connection. It is proved that in the case of geodesic mapping of manifolds with affine connection and when skew-symmetric part of the Ricci tensor is preserved then conformally Fedosov structure is also preserved.

Geodesic Mapping for Dynamic Surface Alignment [PDF]
IEEE Transactions on Pattern Analysis and Machine Intelligence, 2014 This paper presents a novel approach that achieves dynamic surface alignment by geodesing mapping. The surfaces are 3D manifold meshes representing non-rigid objects in motion (e.g., humans) which can be obtained by multiview stereo reconstruction. The proposed framework consists of a geodesic mapping (i.e., geodesic diffeomorphism) between surfaces ...

Modular conjugations in 2D conformal field theory and holographic bit threads
Journal of High Energy Physics, 2022 We study the geometric action of some modular conjugations in two dimensional (2D) conformal field theories. We investigate the bipartition given by an interval when the system is in the ground state, either on the line or on the circle, and in the ...

Geometry of Fisher Information Metric and the Barycenter Map
Entropy, 2015 Geometry of Fisher metric and geodesics on a space of probability measures defined on a compact manifold is discussed and is applied to geometry of a barycenter map associated with Busemann function on an Hadamard manifold \(X\).
