New approaches to modern statistical classification problems
(University of CambridgeDepartment of Pure Mathematics and Mathematical Statistics, 2015-11-10)
This thesis concerns the development and mathematical analysis of statistical procedures for
classification problems. In supervised classification, the practitioner is presented with the
task of assigning an object to ...
Stability and bifurcation for the Kuramoto model
(ElsevierJournal de Mathématiques Pures et Appliquées, 2015-11-11)
We study the mean-field limit of the Kuramoto model of globally coupled oscillators. By studying the evolution in Fourier space and understanding the domain of dependence, we show a global stability result. Moreover, we ...
A More General Pandora Rule?
(ElsevierJournal of Economic Theory, 2015-11-02)
In a model introduced by Weitzman an agent called Pandora opens boxes sequentially, in whatever order she likes, discovers prizes within, and optimally stops. Her aim is to maximize the expected value of the greatest ...
Optimal impartial selection
(Society for Industrial and Applied MathematicsSIAM Journal on Computing, 2015-10-20)
We study a fundamental problem in social choice theory, the selection of a member of a set of agents based on impartial nominations by agents from that set. Studied previously by Alon et al. [Proceedings of TARK, 2011, pp. ...
Critical behaviour in charging of electric vehicles
(IOP PublishingNew Journal of Physics, 2015-09-02)
The increasing penetration of electric vehicles over the coming decades, taken together with the high cost to upgrade local distribution networks and consumer demand for home charging, suggest that managing congestion on ...
The X-ray transform for connections in negative curvature
(SpringerCommunications in Mathematical Physics, 2015-11-23)
We consider integral geometry inverse problems for unitary connections and skew-Hermitian Higgs fields on manifolds with negative sectional curvature. The results apply to manifolds in any dimension, with or without boundary, ...
Remarks on motives of abelian type
(Tohoku Mathematical Journal, 2015-08-11)
A motive over a field k is of abelian type if it belongs to the thick and rigid subcategory of Chow motives spanned by the motives of abelian varieties over k. This paper contains three sections of independent interest. ...
Computing the Cassels-Tate pairing
(University of CambridgeDepartment of Pure Mathematics and Mathematical Statistics, 2015-11-10)
Stability of charged rotating black holes for linear scalar perturbations
(University of CambridgeDepartment of Pure Mathematics and Mathematical StatisticsCambridge Centre for Analysis, 2015-03-03)
In this thesis, the stability of the family of subextremal Kerr-Newman space- times is studied in the case of linear scalar perturbations.
That is, nondegenerate energy bounds (NEB) and integrated local energy decay ...
Unifying Amplitude and Phase Analysis Unifying Amplitude and Phase Analysis. A Compositional Data Approach to Functional Multivariate Mixed-Effects Modeling of Mandarin Chinese
(Taylor & FrancisJournal of the American Statistical Association, 2015-07-06)
Mandarin Chinese is characterized by being a tonal language; the pitch (or F0) of its utterances carries considerable linguistic information. However, speech samples from different individuals are subject to changes in ...
