  • Constrained dynamics and higher derivative systems in modified gravity 

    Chen, Tai-jun (University of CambridgeDepartment of Applied Mathematics and Theoretical Physics, 2015-06-09)
    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 ...

  • Post-inflationary non-Gaussianities on the cosmic microwave background 

    Su, Shi Chun (University of CambridgeDepartment of Applied Mathematics and Theoretical PhysicsTrinity Hall, 2015-06-30)
    The cosmic microwave background (CMB) provides unprecedented details about the history of our universe and helps to establish the standard model in modern cosmology. With the ongoing and future CMB observations, higher ...
