My main research is in
number theory, that is, the study of the properties of the whole
numbers, especially by the use of analytic techniques.
Particular subjects of interest are Waring's problem, the
Goldbach problem, the Hardy-Littlewood method, the use of
y-factorable numbers, i.e. numbers with no prime factors
exceeding y, the distribution of prime numbers, exponential sums
over integer sequences such as the sequence of primes,
properties of the Riemann zeta-function and Dirichlet
L-functions and diophantine approximation.
It can be of no practical use to know that π is irrational, but if we can know, it surely would be intolerable not to know.

A Course of Elementary Number Theory
This is a book based on the elementary number theory courses I have taught over nearly fifty years at Imperial College London and Penn State University. I don't think publishers should charge huge amounts for what can be produced with very little effort.
