dc.description.abstractBASED ON AN EARLIER INTRODUCED NEW CLASS OF GENERALIZED GRAVITY-MATTER MODELS DEFINED IN TERMS OF TWO INDEPENDENT NONRIEMANNIAN VOLUME FORMS (ALTERNATIVE GENERALLY COVARIANT INTEGRATION MEASURE DENSITIES) ON THE SPACE-TIME MANIFOLD, WE DERIVE AN EFFECTIVE ?EINSTEIN-FRAME? THEORY FEATURING THE FOLLOWING REMARKABLE PROPERTIES: (I) WE OBTAIN EFFECTIVE POTENTIAL FOR THE COSMOLOGICAL SCALAR FIELD POSSESSING TWO INFINITELY LARGE FLAT REGIONS WHICH ALLOWS FOR A UNIFIED DESCRIPTION OF BOTH EARLY UNIVERSE INFLATION AS WELL AS OF PRESENT DARK ENERGY EPOCH; (II) FOR A SPECIFIC PARAMETER RANGE THE MODEL POSSESSES A NON-SINGULAR STABLE ?EMERGENT UNIVERSE? SOLUTION WHICH DESCRIBES AN INITIAL PHASE OF EVOLUTION THAT PRECEDES THE INFLATIONARY PHASE.
