Mechanisms of Lagrangian Analyticity in Fluids [PDF]

Archive for Rational Mechanics and Analysis, 2019
Certain systems of inviscid fluid dynamics have the property that for solutions that are only slightly better than differentiable in Eulerian variables, the corresponding Lagrangian trajectories are analytic in time. We elucidate the mechanisms in fluid dynamics systems that give rise to this automatic Lagrangian analyticity, as well as mechanisms in ...

Symmetries in central-force problems [PDF]

Serbian Astronomical Journal, 2003
The two-body problem in central fields (reducible to a central-force problem) models a lot of concrete astronomical situations. The corresponding vector fields (in Cartesian and polar coordinates, extended via collision-blow-up and infinity-blow-up ...

Hyperbolic normal forms and invariant manifolds: Astronomical applications [PDF]

Serbian Astronomical Journal, 2012
In recent years, the study of the dynamics induced by the invariant manifolds of unstable periodic orbits in nonlinear Hamiltonian dynamical systems has led to a number of applications in celestial mechanics and dynamical astronomy.

An analytical solution of boundary problems of shell deformation mechanics [PDF]

MATEC Web of Conferences, 2022
This paper proposes an algorithm for the analytical (with a controllable error) solution of boundary-value problems of shell deformation mechanics. Decomposition of partial differential equations is per-formed.
