Global integrability of cosmological scalar fields
Andrzej J. Maciejewski, Maria Przybylska, Tomasz Stachowiak +1
We investigate the Liouvillian integrability of Hamiltonian systems describing a universe filled with a scalar field (possibly complex). The tool used is the differential Galois gr…
Global dynamics of cosmological scalar fields -- Part II
Andrzej J. Maciejewski, Maria Przybylska, Tomasz Stachowiak +1
This is the second part of integrability analysis of cosmological models with scalar fields. Here, we study systems with conformal coupling, and show that apart from four cases, wh…
Necessary conditions for partial and super-integrability of Hamiltonian systems with homogeneous potentia
Andrzej J. Maciejewski, Maria Przybylska, Haruo Yoshida
We consider a natural Hamiltonian system of degrees of freedom with a homogeneous potential. Such system is called partially integrable if it admits independent and com…
