By Kenji Ueno

Algebraic geometry performs a huge position in numerous branches of technological know-how and know-how. this can be the final of 3 volumes by way of Kenji Ueno algebraic geometry. This, in including Algebraic Geometry 1 and Algebraic Geometry 2, makes a great textbook for a path in algebraic geometry.

In this quantity, the writer is going past introductory notions and provides the speculation of schemes and sheaves with the objective of learning the houses precious for the whole improvement of contemporary algebraic geometry. the most subject matters mentioned within the e-book comprise measurement idea, flat and correct morphisms, normal schemes, delicate morphisms, of entirety, and Zariski's major theorem. Ueno additionally provides the idea of algebraic curves and their Jacobians and the relation among algebraic and analytic geometry, together with Kodaira's Vanishing Theorem.

Their themes are respectively the relationship among algebraic K-theory and the torsion algebraic cycles on an algebraic kind, a brand new method of Iwasawa idea for Hasse-Weil L-function, and the functions of arithemetic geometry to Diophantine approximation.

The Lerch Zeta-function

The Lerch zeta-function is the 1st monograph in this subject, that's a generalization of the vintage Riemann, and Hurwitz zeta-functions. even supposing analytic effects were offered formerly in quite a few monographs on zeta-functions, this can be the 1st ebook containing either analytic and likelihood thought of Lerch zeta-functions.
