From Euclidean Black Hole to a Bouncing Cosmology
with Ram BrusteinAbstract/Description: This thesis introduces a novel two-dimensional cosmological model of a bouncing
cosmology, in which the universe contracts until a certain point and then
expands. Using a two-dimensional string action; including a winding condensate
and the dilaton scalar field, we obtain a model that allows the possibility
of a non-singular bounce. Utilizing a non-singular Euclidean Black
Hole solution, an analytic continuation of space and time, and a coordinate
transformation, we successfully construct the desired bouncing cosmology
solution featuring a non-singular contracting and then expanding universe.
