Constrained dynamics and higher derivative systems in modified gravity
In this thesis, higher derivative theories and constrained dynamics are investigated in detail. In the first part of the thesis, we discuss how the Ostrogradski instability emerges in non-degenerate higher derivative theories in the context of a one-dimensional point particle where the position of …

The origin of inflation.
… evidence for a pe1iod of inflation from M-theory. Moreover, whether inflation actually occurs within a given theory is known to depend strongly on the initial conditions. These conceptual problems of inflation are the driving force behind the research presented in this thesis. We study …
