This book continues the applications of mathematics, more specifically of theta, eta, and zeta functions, and modular forms, to various areas of theoretical physics. It is a follow-up and extension in some sense of the author's earlier book entitled A window into zeta and modular physics. Some of the main topics are

1. A new approach to logarithmic corrections to black hole entropy

2. My recent work that provides for an explicit cold plasma-black hole connection

3. Generalization of work of physicists on certain asymptotic problems relating to string theory, for example,...
