Connections among three roads to cosmic acceleration: decaying vacuum, bulk viscosity, and nonlinear fluids
Sandro Silva e Costa, Martin Makler
We discuss the connection among three distinct classes of models often used to explain the late cosmic acceleration: decaying cosmological term, bulk viscous pressure, and nonlinea…

Casimir energy in finite expanding universes: a prelude
Sandro Silva e Costa, Reuven Opher
We present the Green's functions that are the solutions of the massive Klein-Gordon equation for a scalar field with non-minimal coupling to gravitation for several static and expa…

Generalizing the MOND description of rotation curves
Sandro S. e Costa, R. Opher
We present new mathematical alternatives for explaining rotation curves of spiral galaxies in the MOND context. For given total masses, it is shown that various mathematical altern…
