CAT - Complex analysis: techniques, applications and computations

Employing techniques of complex analysis, three different problems will be discussed: (i) Initial-boundary value problems via the unified
transform (also known as the Fokas method,www.wikipedia.org/wiki/Fokas_method)[1]. (ii) The evaluation of the large t-asymptotics to all orders of the Riemann zeta function2, and the introduction of a new approach to the Lindelöf Hypothesis3. (iii) A novel analytical algorithm for the medical technique of SPECT and its numerical implementation [4].
