GEODESIC VECTORS ON $5$-DIMENSIONAL HOMOGENEOUS NILMANIFOLDS

Matematički Vesnik
Summary: In this paper, firstly we study geodesic vectors for the \(m\)-th root homogeneous Finsler space admitting \((\alpha,\beta)\)-type. Then we obtain the necessary and sufficient condition for an arbitrary non-zero vector to be a geodesic vector for the \(m\)-th root homogeneous Finsler metric under mild conditions. Finally, we consider a quartic

Integrable geodesic flows of Riemannian and sub-Riemannian metrics on Lie groups and homogeneous spaces [PDF]

, 2014
We discuss general algebraic methods for constructing integrable geodesic flows of Riemannian and sub-Riemannian metrics on homogeneous spaces and Lie groups. Our approach is based on the concept of non-commutative integrability and the classical idea of

Metamorphic Dehydration, Fluid Pressure, and the Frictional‐Viscous Transition Along Subduction Megathrusts: Case Study in Cascadia and Implications for Slow Earthquakes

AGU Advances, Volume 7, Issue 3, June 2026.
Abstract Relative plate motion in subduction zones transitions from frictional slip to viscous flow with increasing depth and temperature. The frictional‐viscous transition can control the depth extent of megathrust earthquakes and episodic tremor and slip (ETS).

A note on geodesic and almost geodesic mappings of homogeneous Riemannian manifolds

Tyt. z nagł.Abstract. Let M be a differentiable manifold and denote by nabla and nabla~ two linear connections on M. Nabla and nabla~ are said to be geodesically equivalent if and only if they have the same geodesics.

Homogeneous geodesics of non-reductive homogeneous pseudo-Riemannian 4-manifolds

, 2015
After obtaining an explicit description in global coordinates of invariant metrics on four-dimensional non-reductive homogeneous pseudo-Riemannian manifolds, for each of these spaces we completely describe Killing and geodesic vector elds and ...

New Insights Into Hikurangi Subduction Inputs and Megathrust Host Rocks Spanning Along‐Margin Changes in Fault Slip Behavior

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 6, June 2026.
Abstract The seismic behavior of subduction megathrusts varies spatially and is influenced by the properties of subducting plates, including their sedimentary cover. Characterizing these subduction inputs is essential for understanding the mechanisms behind fault slip variability.

Importance of Spatially Continuous Urban Surface Properties in Urban‐Resolving Earth System Modeling

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 6, June 2026.
Abstract Accurate representation of urban properties and processes at higher resolutions in global modeling systems is essential for advancing our ability to capture the complexities of urban systems and informing effective resilience strategies. However, the prescription of coarse global‐scale urban properties in most state‐of‐the‐art Earth system ...

Arc Heat Flow and Magmatic Heat Budgets

Reviews of Geophysics, Volume 64, Issue 2, June 2026.
Abstract We evaluate hydrothermal heat loss from 11 volcanic‐arc segments (∼6,000 km of arc length, ∼10% of the global total), motivated by the observation that much magmatic heat ultimately crosses the land surface as heated aqueous fluid. Heat loss takes place by volcanic eruption, geothermal heat conduction to the surface, fumarolic (vapor ...

Differing Manifestations of Spatial Curvature in Cosmological FRW Models

Universe
We found statistical evidence for a mismatch between the (global) spatial curvature parameter K in the geodesic equation for incoming photons and the corresponding parameter in the Friedmann equation that determines the time evolution of the background ...

Two‐Layer Anisotropy Beneath Subduction Zones: Bayesian Inversion

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 6, June 2026.
Abstract Shear‐wave splitting measurements have the potential to constrain multiple layers of anisotropy and thereby enhance depth resolution. Using the formulation of Silver and Savage (1994, https://doi.org/10.1111/j.1365‐246x.1994.tb04027.x), previous studies have employed deterministic grid‐search approaches to identify best‐fitting two‐layer ...
