Articles and notes by Tim Jameson

My son Tim (alias Timothy or T.P.) died tragically on 5 September 2013. He was passionately keen on mathematics, though he did not complete a Ph. D. or hold a paid position.

The following is a selection of his mathematical writings, both published and unpublished, The unpublished ones were generally notes intended only for his own use, but some of them may be of interest to a wider audience. Most of them lacked a list of references which I have endeavoured to supply.

The probability integral by volume of revolution (Math. Gazette, 1994)

Another proof that zeta(2) = pi^2/6 by double integration (Math Gazette, 2013)

Orbits made easy by complex numbers (Math. Gazette, 2014)

Some double series related to zeta(3) (Math. Gazette, 2014)

Polylogarithms, multiple zeta values, and the series of Hjortnaes and Comtet

An elementary derivation of the Poisson summation formula

The fourth power moment of zeta(1/2 + it)

The approximate functional equation for zeta(s)^2

The Ingham-Huxley zero-density theorem

Linnik's proof of the Waring-Hilbert theorem from Hua's book (with a mistake corrected)

The Gauss circle problem (the classical exponent 1/3)

Integrating the error in the divisor problem

Daboussi's version of Vinogradov's bound for the exponential sum over primes
