Le formule del grado
Questo manoscritto è un'introduzione al concetto di formule del grado e a qualche loro applicazione. In esso si dà una formalizzazione di quello che si intenderà con formula del grado, vengono enunciati due esempi: uno cosiddetto di primo livello ed uno più generale. Successivamente si descrivono le componenti di queste formule: i numeri e gli ideali di ostruzione. Dopo un breve accenno alla dimostrazione, il testo si conclude con una sezione in cui si analizzano esplicitamente varietà algebriche...

Les motifs de Tate et les opérateurs de périodicité de Connes
Dans cet article, nous définissons une catégorie des motifs sur une catégorie monoïdale symétrique vérifiant certaines hypothèses. Le rôle des espaces sur est joué par les monoïdes (non necessairement commutatifs) dans . Pour définir les morphismes dans , nous utilisons des classes dans les groupes d’homologie cyclique bivariante. Le but est de montrer que les opérateurs de périodicité de Connes induisent des morphismes dans , où est le motif de Tate dans .
Lie perfect, Lie central extension and generalization of nilpotency in multiplicative Lie algebras
This paper aims to introduce and explore the concept of Lie perfect multiplicative Lie algebras, with a particular focus on their connections to the central extension theory of multiplicative Lie algebras. The primary objective is to establish and provide proof for a range of results derived from Lie perfect multiplicative Lie algebras. Furthermore, the study extends the notion of Lie nilpotency by introducing and examining the concept of local nilpotency within multiplicative Lie algebras. The...
Loop spaces of the Q-construction
Giffen in [1], and Gillet-Grayson in [3], independently found a simplicial model for the loop space on Quillen's Q-construction. Their proofs work for exact categories. Here we generalise the results to the K-theory of triangulated categories. The old proofs do not generalise. Our new proof, aside from giving the generalised result, can also be viewed as an amusing new proof of the old theorems of Giffen and Gillet-Grayson.
