Algèbre 2 - version finale

Also, W — 82 is a closed semi analytic set in C 2 of dimension at most one, and can hence be written as So u Si where So is a finite set of points and Si is a relatively

We study the ∗ q-torsion freeness of the symmetric algebra of a finitely generated graded module E over a ∗ G q -ring and we state the graded versions of some classical results

Using Cayley graphs and Clifford algebras, we are able to give, for every finitely generated groups, a uniform construction of spec- tral triples with a generically non-trivial

In Section 2 we recall some defini- tions and facts related to compact quantum groups, free wreath product by quantum permutation group and quantum isometry group of spectral

In contrast to Boolean algebras, finitely generated free Heyting algebras are infinite, as was shown in the first article on Heyting algebras by McKinsey and Tarski in the 1940s.. For

The investigation of abe- lian groups with respect to endoprimality was started by Davey and Pit- kethly [1] who, beside results for other kinds of algebraic structures, de-

answer to the following question of the author (see [3]): is a soluble group polycyclic if all centralizers of its finitely generated subgroups.. are finitely

We present here an example of directed, torsion-free, non Archimedean, finitely presented partially ordered abelian group G. Thus G is a finitely presented partially ordered
