Other new sequences are introduced in number theory, and for each one a general question: how many primes each sequence has.

Over 300 sequences and many unsolved problems and conjectures related to them are presented herein. The book contains definitions, unsolved problems, questions,

This advanced graduate textbook gives an authoritative and insightful description of the major ideas and techniques of public key cryptography.

Recurrence sequences are of great intrinsic interest and have been a central part of number theory for many years. Moreover, these sequences appear almost every

Analytic combinatorics aims to enable precise quantitative predictions of the properties of large combinatorial structures. The theory has emerged over recent d
