Inhomogeneous initial data and small-field inflation
(IoPJournal of Cosmology and Astroparticle Physics, 2018-05-08)
We consider the robustness of small-field inflation in the presence of scalar field inhomo- geneities. Previous numerical work has shown that if the scalar potential is flat only over a narrow in- terval, such as in commonly ...
ADHM and the 4d quantum Hall effect
(Journal of High Energy Physics, 2018-04-01)
© 2018, The Author(s). Yang-Mills instantons are solitonic particles in d = 4 + 1 dimensional gauge theories. We construct and analyse the quantum Hall states that arise when these particles are restricted to the lowest ...
The calculation of sparticle and Higgs decays in the minimal and next-to-minimal supersymmetric standard models: SOFTSUSY4.0
(ElsevierComputer Physics Communications, 2017-11-01)
We describe a major extension of the SOFTSUSY spectrum calculator to include
the calculation of the decays, branching ratios and lifetimes of sparticles
into lighter sparticles, covering the next-to-minimal supersymmetric ...
Z′ models for the LHCb and g-2 muon anomalies

Maximum likelihood estimation of a multivariate log-concave density
(University of Cambridge, 2010-01-12)
Density estimation is a fundamental statistical problem. Many methods are either
sensitive to model misspecification (parametric models) or difficult to calibrate, especially
for multivariate data (nonparametric smoothing ...
Iwasawa theory for modular forms at supersingular primes
(University of CambridgeDepartment of Pure Mathematics and Mathematical Statistics, 2010-07-06)
Let f=\sum a_nq^n be a normalised eigen-newform of weight k\ge2 and p an odd prime which does not divide the level of f. We study a reformulation of Kato's main conjecture for f over the Zp-cyclotomic extension of Q. In ...
Cliques in graphs
(University of CambridgeDepartment of Pure Mathematics and Mathematical Statistics, 2010-10-12)
The main focus of this thesis is to evaluate $k_r(n,\delta)$, the minimal number of $r$-cliques in graphs with $n$ vertices and minimum degree~$\delta$. A fundamental result in Graph Theory states that a triangle-free graph ...
Non-commutative Iwasawa theory of elliptic curves at primes of multiplicative reduction
(University of CambridgeDepartment of Pure Mathematics and Mathematical Statistics, 2010-07-06)
Let E be an elliptic curve defined over the rationals Q, and p be a prime at least 5 where E has multiplicative reduction. This thesis studies the Iwasawa theory of E over certain false Tate curve extensions F[infinity], ...
Witt groups of complex varieties
(University of CambridgeDepartment of Pure Mathematics and Mathematical StatisticsTrinity Hall, 2011-07-12)
The thesis Witt Groups of Complex Varieties studies and compares two related cohomology theories that arise in the areas of algebraic geometry and topology: the algebraic theory of Witt groups, and real topological K-theory. ...
Response to: DNA identification by pedigree likelihood ratio accommodating population substructure and mutations
(2011-03-25)
Abstract Mutation models are important in many areas of genetics including forensics. This letter criticizes the model of the paper 'DNA identification by pedigree likelihood ratio accommodating population substructure and ...
