This paper examines a new Noether theorem for Hamiltonian systems with Caputo Δ derivatives based on fractional time-scales calculus, which overcomes the difficulties unified …

In this paper we aim at presenting a concise but also comprehensive study of time- dependent (t-dependent) Hamiltonian dynamics on a locally conformal symplectic (lcs) …
In this paper we present an approach toward the comprehensive analysis of the nonintegrability of differential equations in the form ̈x=f(x,t) which is analogous to …

For the motion of a charged particle in a uniform, time-dependent axial magnetic field B (t) ez, it is shown that there is an exact magnetic-moment invariant of the particle dynamics M …
The Equivalence Principle is considered in the framework of metric-affine gravity. We show that it naturally emerges as a Noether symmetry starting from a general non-metric theory. In …
