New Frontiers in Number Theory and Applications

This contributed volume presents recent advances as well as new directions in number theory and its applications. Algebraic and analytic number theory are the main focus with chapters showing how these areas are rapidly evolving. By gathering authors from over seven countries, readers will gain an international perspective on the current state of research as well as potential avenues to explore. Specific topics covered include:

• Algebraic Number Theory
• Elliptic curves and Cryptography
• Hopf Galois theory
• Analytic and elementary number theory and applications New Frontiers in Number Theory and Applications will appeal to researchers interested in gaining a global view of current research in number theory.

Presents recent advances as well as new directions in number theory and its applications Shows the rapid evolution of the field with a particular focus on analytic and algebraic number theory Offers an international perspective on the current state and future directions of these research areas
