Quadratic and hermitian forms over rings

This publication provides the speculation of quadratic and hermitian varieties over jewelry in a truly normal environment. It avoids, so far as attainable, any limit at the attribute and takes complete good thing about the functorial homes of the idea. it isn't an encyclopedic survey. It stresses the algebraic elements of the speculation and avoids - is reasonably overlapping with different books on quadratic types (like these of Lam, Milnor-Husemöller and Scharlau).

Liaison, Schottky Problem and Invariant Theory: Remembering Federico Gaeta

This quantity is a homage to the reminiscence of the Spanish mathematician Federico Gaeta (1923-2007). except a old presentation of his lifestyles and interplay with the classical Italian college of algebraic geometry, the amount provides surveys and unique examine papers at the arithmetic he studied.

Automorphisms in Birational and Affine Geometry: Levico Terme, Italy, October 2012

The main target of this quantity is at the challenge of describing the automorphism teams of affine and projective types, a classical topic in algebraic geometry the place, in either instances, the automorphism team is usually limitless dimensional. the gathering covers a variety of themes and is meant for researchers within the fields of classical algebraic geometry and birational geometry (Cremona teams) in addition to affine geometry with an emphasis on algebraic staff activities and automorphism teams.

Tn is generated by {t1 , . . , tN }. In particular, for every ring R , the ideal (t1 , t2 , . ) ⊆ R[x1 , . . , xn ] is finitely generated. 44 1. Foundations αn 1 Proof. The map log : Tn → Nn given by xα → (α1 , . . , αn ) is 1 · · · xn clearly an isomorphism of monoids. The monoideal (log(t1 ), log(t2 ), . ) ⊆ Nn is finitely generated by the previous proposition. Thus there exists a number N > 0 such that this monoideal is generated by {log(t1 ), . . , log(tN )}. Consequently, the monoideal (t1 , t2 , .
