Class number one criterion for some non-normal totally real cubic fields
Let be the family of non-normal totally real cubic
number fields defined by the irreducible cubic polynomial
, where is an integer with . In this
paper, we will give a class number one criterion for .Comment: 9 page
Feynman's sunshine numbers
This is an expansion of a talk for mathematics and physics students of the
Manchester Grammar and Manchester High Schools. It deals with numbers such as
the Riemann zeta value zeta(3)=sum_{n>0}1/n^3. Zeta values appear in the
description of sunshine and of relics from the Big Bang. They also result from
Feynman diagrams, which occur in the quantum field theory of fundamental
particles such as photons, electrons and positrons. My talk included 7
reasonably simple problems, for which I here add solutions, with further
details of their context.Comment: 24 pages, LaTe
On the Holography of Free Yang-Mills
We study the AdS/CFT duality where the boundary CFT is free
Yang-Mills theory with gauge group SU(N). At the planar level we use the
spectrum and correlation functions of the boundary theory to explicate features
of the bulk theory. Further, by computing the one-loop partition function of
the bulk theory using the methods of arXiv:1603.05387, we argue that the bulk
coupling constant should be shifted to from . Similar conclusions
are reached by studying the dualities in thermal AdS with
boundary.Comment: 44 pages, version to appear in JHE
Nonvanishing of twists of -functions attached to Hilbert modular forms
We describe algorithms for computing central values of twists of
-functions associated to Hilbert modular forms, carry out such computations
for a number of examples, and compare the results of these computations to some
heuristics and predictions from random matrix theory.Comment: 19 page
