Zeta and \(L\)-functions in Number Theory and Combinatorics

A co-publication of the AMS and CBMS
Zeta and \(L\)-functions play a central
role in number theory. They provide important information of
arithmetic nature. This book, which grew out of the author's teaching
over several years, explores the interaction between number theory and
combinatorics using zeta and \(L\)-functions as a central theme. It
provides a systematic and comprehensive account of these functions in
a combinatorial setting and establishes, among other things, the
combinatorial counterparts of celebrated results in number theory,
such as the prime number theorem and the Chebotarev density theorem.
The spectral theory for finite graphs and higher dimensional
complexes is studied. Of special interest in theory and applications
are the spectrally extremal objects, called Ramanujan graphs and
Ramanujan complexes, which can be characterized by their associated
zeta functions satisfying the Riemann Hypothesis. Explicit
constructions of these extremal combinatorial objects, using
number-theoretic and combinatorial means, are presented.
Research on zeta and \(L\)-functions for complexes other
than graphs emerged only in recent years. This is the first book for
graduate students and researchers offering deep insight into this
fascinating and fast developing area.
Readership
