Having recently read a review that expounded on the rigour and depth of books by 'earlier' British mathematicians (mainly analysts) I would like to know more. My own research yielded the following tentative list, which I believe to be relatively incomplete and shallow:
- G. H. Hardy, A Course of Pure Mathematics.
- G. H. Hardy, E. M. Wright, An Introduction to the Theory of Numbers.
- E. C. Titchmarsh, The Theory of Functions.
- E. W. Hobson, The Theory of Functions of a Real Variable and the Theory of Fourier's Series (2 vols.).
- E. T. Copson, An Introduction to the Theory of Functions of a Complex Variable.
- Alfred North Whitehead, Bertrand Russell, Principia Mathematica.
- G. S. Carr, Synopsis of Pure Mathematics (2 vols.).
I'm certain that there are many other classics, concentrated most probably in the early or mid-20th century. Any suggestions would be greatly appreciated.
