A general model for time-minimizing navigation on a mountain slope under gravity

Nicoleta Aldea, Piotr Kopacz

In this work, we solve the generalized Matsumoto's slope-of-a-mountain problem by means of Riemann-Finsler geometry, making close links with the Zermelo navigation problem. The tim…

Time geodesics on a slippery cross slope under gravitational wind

Nicoleta Aldea, Piotr Kopacz

In this work, we pose and solve the time-optimal navigation problem considered on a slippery mountain slope modeled by a Riemannian manifold of an arbitrary dimension, under the ac…

Generalized Zermelo navigation on Hermitian manifolds under mild wind

Nicoleta Aldea, Piotr Kopacz

We generalize and study the Zermelo navigation problem on Hermitian manifolds in the presence of a perturbation determined by a mild complex velocity vector field $||W(z)||_h<|…

A note on time-optimal paths on perturbed spheroid

Piotr Kopacz

We consider the Zermelo navigation problem on the ellipsoid of revolution (spheroid) in the presence of a perturbation determined by a mild velocity vector field, , with…

Application of planar Randers geodesics with river-type perturbation in search models

Piotr Kopacz

We consider remodeling the planar search patterns, in the presence of the river-type perturbation represented by the weak vector field, basing on the time-optimal paths as Finsleri…
