The objective of this book is to look at certain commutative graded algebras that appear
frequently in algebraic geometry. By studying classical constructions from geometry from the …

This volume contains the proceedings of the Workshop in Commutative Algebra, held at
Salvador (Brazil) on August 8-17, 1988. A few invited papers were included which were not …

As a commutative algebraist one has time and again found oneself intrigued by the way in
which differentials and derivations play their frequently unexpected act in ring and module …

Let A be a K-subalgebra of the polynomial ring S= K x_1, ..., x_d S= K x 1,…, xd of dimension
d, generated by finitely many monomials of degree r. Then, the Gauss algebra G (A) G (A) of …

Given a standard graded polynomial ring R= k [x1,…, xn] over a field k of characteristic zero
and a graded k-subalgebra A= k [f1,…, fm]⊂ R, one relates the module ΩA/k of Kähler k …

Estas notas constituem um roteiro para um ciclo de conferências proferidas no
Departamento de Matemática da FCUP. Como tal, nao inclui as demonstraçoes da grande …

The representation theory of finite groups is now more than 100 years old. Its foundations
were laid down by Frobenius, Burnside, Schur and, later, Brauer. It was Frobenius and …
