Algebre di Łukasiewicz quasi-locali Stoneane

Francesco Lacava (2001)

Bollettino dell'Unione Matematica Italiana

Similarity:

We prove some properties of quasi-local Ł-algebras. These properties allow us to give a structure theorem for Stonean quasi-local Ł-algebras. With this characterization we are able to exhibit an example which provides a negative answer to the first problem posed in [4].

Numerical characters of graded algebras

Giuseppe Valla (2004)

Bollettino dell'Unione Matematica Italiana

Similarity:

This is the summary of the plenary talk I gave in Milan at the XVII Meeting of the Unione Matematica Italiana. We focus on some relevant numerical characters of the standard graded algebras and, in some case, we explain their geometric meaning.
