Wave functions for arbitrary operator ordering in the de Sitter minisuperspace approximation
(University of Canterbury. Physics and Astronomy, 2000)
We derive exact series solutions for the Wheeler-DeWitt equation corresponding to a spatially closed Friedmann-Robertson-Walker universe with cosmological constant for arbitrary operator ordering of the scale factor of ...
What is general relativity?
General relativity is a set of physical and geometric principles, which lead to a set of (Einstein) field equations that determine the gravitational field, and to the geodesic equations that describe light propagation ...
Lagrangian theory of structure formation in relativistic cosmology. V. Irrotational fluids
We extend the general relativistic Lagrangian perturbation theory, recently developed for the formation of cosmic structures in a dust continuum, to the case of model universes containing a single fluid with a single–valued ...
Scaling Laws of Droplet Coalescence: Theory and Numerical Simulation
When two Newtonian liquid droplets are brought into contact on a solid substrate, a highly curved meniscus neck is established between the two which transforms the bihemispherically shaped fluid domain to a hemispherically ...
