Geodesic motion in the space-time of a noncompact boson star [PDF]
, 2013 We study the geodesic motion of test particles in the space-time of noncompact boson stars. These objects are made of a self-interacting scalar field and---depending on the scalar field's mass---can be as dense as neutron stars or even black holes.

Constraints on the interacting vacuum–geodesic CDM scenario [PDF]
Monthly notices of the Royal Astronomical Society, 2019 We investigate an interacting dark sector scenario in which the vacuum energy is free to interact with cold dark matter (CDM), which itself is assumed to cluster under the sole action of gravity, i.e. it is in freefall (geodesic), as in ΛCDM.

Uniform Convexity and Convergence of a Sequence of Sets in a Complete Geodesic Space
Abstract and Applied Analysis, 2022 In this paper, we first introduce two new notions of uniform convexity on a geodesic space, and we prove their properties. Moreover, we reintroduce a concept of the set-convergence in complete geodesic spaces, and we prove a relation between the metric ...

, 2013 In this paper, we deal with the Halpern iterative scheme for a strongly quasinonexpansive mapping in the setting of a complete geodesic space with curvature bounded above by one. Our result can be applied to the image recovery problem.

Deep Geodesic Learning for Segmentation and Anatomical Landmarking [PDF]
IEEE Transactions on Medical Imaging, 2018 In this paper, we propose a novel deep learning framework for anatomy segmentation and automatic landmarking. Specifically, we focus on the challenging problem of mandible segmentation from cone-beam computed tomography (CBCT) scans and identification of

Products of hyperbolic metric spaces [PDF]
, 2002 Let (X_i,d_i), i=1,2, be proper geodesic hyperbolic metric spaces. We give a general construction for a ``hyperbolic product'' X_1{times}_h X_2 which is itself a proper geodesic hyperbolic metric space and examine its boundary at infinity.Comment: 17 ...

The shape space of discrete orthogonal geodesic nets
ACM Transactions on Graphics, 2018 Discrete orthogonal geodesic nets (DOGs) are a quad mesh analogue of developable surfaces. In this work we study continuous deformations on these discrete objects. Our main theoretical contribution is the characterization of the shape space of DOGs for a

Teichm\"uller Space Is Totally Geodesic In Goldman Space [PDF]
, 2013 We construct a new Riemannian metric on Goldman space $\mathcal{B}(S)$, the space of the equivalence classes of convex projective structures on the surface $S$, and then prove the new metric, as well as the metric of Darvishzadeh and Goldman, restricts ...

Construction of Developable Surface with Geodesic or Line of Curvature Coordinates
Journal of New Theory, 2021 In this paper, a developable surface with geodesic or line of curvature coordinates is constructed in the Euclidean 3-space. A developable surface is coordinated by two families of parametric curves, base curves (directrices) and lines (rulings).

Low energy dynamics of a CP^1 lump on the sphere [PDF]
, 1995 Low-energy dynamics in the unit-charge sector of the CP^1 model on spherical space (space-time S^2 x R) is treated in the approximation of geodesic motion on the moduli space of static solutions, a six-dimensional manifold with non-trivial topology and ...
