An informative and useful account of complex numbers that includes historical anecdotes, ideas for further research, outlines of theory and a detailed analysis of the ever-elusory Riemann hypothesis. Stephen Roy assumes no detailed mathematical knowledge on the part of the reader and provides a fascinating description of the use of this fundamental idea within the two subject areas of lattice simulation and number theory. Complex Numbers offers a fresh and critical approach to research-based implementation of the mathematical concept of imaginary numbers. Detailed coverage includes:
  • Riemann's zeta function: an investigation of the non-trivial roots by Euler-Maclaurin summation.
  • Basic theory: logarithms, indices, arithmetic and integration procedures are described.
  • Lattice simulation: the role of complex numbers in Paul Ewald's important work of the I 920s is analysed.
  • Mangoldt's study of the xi function: close attention is given to the derivation of N(T) formulae by contour integration.
  • Analytical calculations: used extensively to illustrate important theoretical aspects.
  • Glossary: over 80 terms included in the text are defined.
  • Offers a fresh and critical approach to the research-based implication of complex numbers
  • Includes historical anecdotes, ideas for further research, outlines of theory and a detailed analysis of the Riemann hypothesis
  • Bridges any gaps that might exist between the two worlds of lattice sums and number theory

Roy, S CDr. Stephen Campbell Roy from the green and pleasant Scottish town of Maybole in Ayreshire, received his secondary education at the Carrick Academy, and then studied chemistry at Heriot-Watt University, Edinburgh where he was awarded a BSc (Hons.) in 1991. Moving to St Andrews University, Fife he studied electro-chemistry and in 1994 was awarded his PhD. He then moved to Newcastle University for work in postdoctoral research until 1997. Then to Manchester University as a temporary Lecturer in Chemistry to teach electrochemistry and computer modelling to undergraduates.
