Cosmology and Gravitational Bags via Metric Independent Volume Form Dynamics

Alternative spacetime volume forms generally covariant integration measure densitites independent on the pertinent Riemannian spacetime metric have profound impact in all generally covariant theories in particular producing a new mechanism of dynamical generation of cosmological constant and an associated new mechanism of dynamical spontaneous breakdown of supersymmetry in supergravity and a new type of quintessential inflation scenario in cosmology Coupling of non Riemannian volume form gravity matter theories to a special non standard kind of nonlinear gauge system containing the square root of standard Maxwell Lagrangian yields charge confinement deconfinement phases associated with gravitational electrovacuum bags
