    Horacio Arló-Costa fue sin dudas uno de los principales lógicos que ha producido nuestra Facultad de Filosofía y Letras. Fue, además, una de las principales fuerzas detrás de la consolidación, a nivel mundial, del ámbito de reflexión conocido con el nombre de “epistemología formal”, una disciplina nueva constituida en la intersección de la lógica epistémica, la teoría de la decisión, la inferencia ampliativa y la teoría del conocimiento tradicional

    Generalized belief change with imprecise probabilities and graphical models

    We provide a theoretical investigation of probabilistic belief revision in complex frameworks, under extended conditions of uncertainty, inconsistency and imprecision. We motivate our kinematical approach by specializing our discussion to probabilistic reasoning with graphical models, whose modular representation allows for efficient inference. Most results in this direction are derived from the relevant work of Chan and Darwiche (2005), that first proved the inter-reducibility of virtual and probabilistic evidence. Such forms of information, deeply distinct in their meaning, are extended to the conditional and imprecise frameworks, allowing further generalizations, e.g. to experts' qualitative assessments. Belief aggregation and iterated revision of a rational agent's belief are also explored

    Iterative Probability Kinematics

    Following the pioneer work of Bruno De Finetti, conditional probability spaces (allowing for conditioning with events of measure zero) have been studied since (at least) the 1950's
