  • Spectral methods and computational trade-offs in high-dimensional statistical inference 

    Wang, Tengyao (Department of Pure Mathematics and Mathematical Statistics, University of CambridgeUniversity of CambridgeDepartment of Pure Mathematics and Mathematical StatisticsFaculty of MathematicsSt John's College, 2016-10-04)
    Spectral methods have become increasingly popular in designing fast algorithms for modern highdimensional datasets. This thesis looks at several problems in which spectral methods play a central role. In some cases, we ...

  • Zonal flows in accretion discs and their role in gravito-turbulence 

    Vanon, Riccardo (University of CambridgeDepartment of Applied Mathematics and Theoretical Physics (DAMTP)St Edmund's, 2017-10-01)
    This thesis focuses on the evolution of zonal flows in self-gravitating accretion discs and their resulting effect on disc stability; it also studies the process of disc gravito-turbulence, with particular emphasis given ...
