Abstract:
In this thesis we present a detailed introduction to loop quantum cosmology focusing on the Robertson-Walker cosmologies with constant spatial curvature. The construction of the quantum theory will be presented starting from the classical reduction of the action and will not require prior knowledge of the loop quantum gravity. Particular attention will be paid to the detailed inputs and ambiguities of the quantization and the resulting consequences. We will uncover features of the theory that appear unphysical and propose a new quantization as well as interpretation of the theory that can solve these problems.
