{0,1} e [0,1]: dalla logica quantistica alla logica quantistica fuzzy

Abstract: “We investigate certain Brouwer-Zadeh lattices that serve as abstract counterparts of lattices of effects in Hilbert spaces under the spectral ordering. These algebras, called PBZ*-lattices, can also be seen as generalizations of orthomodular lattices and are remarkable for the collapse of three notions of “sharpness” that are distinct in general Brouwer-Zadeh lattices. We will finally present the structure theory of PBZ*-lattices and we provide an initial description of the lattice of PBZ*-varieties”.

Understanding Causation: A Statistician’s View

Abstract: “The potential outcome approach to causal inference will be introduced. This approach, known also as the Rubin Causal Model, views causal inference as a missing data framework embedded within a Bayesian model based approach. Causal models will be contrasted with associational models of statistical dependence”.
