The plane symmetric Einstein-dust system with positive cosmological constant
S. B. Tchapnda
The Einstein equations with a positive cosmological constant are coupled to the pressureless perfect fluid matter in plane symmetry. Under suitable restrictions on the initial data…
On surface-symmetric spacetimes with collisionless and charged matter
Sophonie Blaise Tchapnda
Some future global properties of cosmological solutions for the Einstein-Vlasov-Maxwell system with surface symmetry are presented. Global existence is proved, the homogeneous spac…
Global existence and asymptotic behaviour in the future for the Einstein-Vlasov system with positive cosmological constant
S. B. Tchapnda, A. D. Rendall
The behaviour of expanding cosmological models with collisionless matter and a positive cosmological constant is analysed. It is shown that under the assumption of plane or hyperbo…
The surface-symmetric Einstein-Vlasov system with cosmological constant
Sophonie Blaise Tchapnda, Norbert Noutchegueme
The results on local existence and continuation criteria obtained by G. Rein in [4] are extended to the case with a non-zero cosmological constant. It is also shown that for the sp…
