The Astronomical JournalWe present an implementation-oriented relativistic modeling framework for high-precision GNSS processing consistent with the IAU-adopted Geocentric and Barycentric Celestial Reference Systems (G CRS /B CRS ) and their associated timescales ( TCB/TDB and ...

Geodesics in metrical connections
, 1971 To each connection on a Riemannian manifold we define a tensor called the Q-tensor. We prove that two metrical connections have the same geodesics if and only if their Q-tensors are equal.

New constraints on the postglacial evolution of Lago Maggiore, Northern Italy
Journal of Quaternary Science, EarlyView.ABSTRACT Lago Maggiore is situated in an overdeepened valley reach at the southern margin of the European Alps, and its thick sediment infill allows the reconstruction of the postglacial valley and lake evolution. We study here the sedimentary succession in the lower Ossola Valley, which is infilled by ~500 m of deposits. In a marginal position, a core

Compact Riemannian Manifolds with Homogeneous Geodesics
Symmetry, Integrability and Geometry: Methods and Applications, 2009 A homogeneous Riemannian space (M = G/H,g) is called a geodesic orbit space (shortly, GO-space) if any geodesic is an orbit of one-parameter subgroup of the isometry group G. We study the structure of compact GO-spaces and give some sufficient conditions

Journal of Differential Geometry, 2010 We consider Kobayashi geodesics in the moduli space of abelian varieties A_g that is, algebraic curves that are totally geodesic submanifolds for the Kobayashi metric. We show that Kobayashi geodesics can be characterized as those curves whose logarithmic tangent bundle splits as a subbundle of the logarithmic tangent bundle of A_g. Both Shimura curves

Geodesics in Brownian surfaces (Brownian maps)
, 2014 International audienceWe define a class a metric spaces we call Brownian surfaces, arising as the scaling limits of random maps on general orientable surfaces with a boundary and we study the geodesics from a uniformly chosen random point.

Limnology and Oceanography: Methods, EarlyView.Abstract The integration of high‐throughput image–based flow cytometry into routine phytoplankton assessment requires rigorous evaluation against established microscopy techniques. As method agreement is often site‐ and species‐specific, case‐by‐case validation is essential to successfully adopt emerging methods.

Mathematical Methods in the Applied Sciences, Volume 48, Issue 6, Page 6912-6917, April 2025.ABSTRACT Nowadays, a substantial portion of investigations concerning the symmetry analysis of differential equations predominantly adhere to a framework comprising the following key procedures: (i) the derivation of symmetries, (ii) the determination of an optimal system, (iii) the utilization of these symmetries to construct invariants or ...

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 ...

Optimal three-dimensional biped walking pattern generation based on geodesics
International Journal of Advanced Robotic Systems, 2017 The innovative three-dimensional humanoid biped gait planning method using geodesics is introduced in this article. In order to control three-dimensional walking, the three-dimensional linear inverted pendulum model is studied in our energy-optimal gait ...
