Pettis property for Polish inverse semigroups
Karen Arana, Jerson Perez, Carlos Uzcategui
We study a property about Polish inverse semigroups similar to the classical theorem of Pettis about Polish groups. In contrast to what happens with Polish groups, not every Polish…
Topologies on the symmetric inverse semigroup
J. Perez, C. Uzcategui
The symmetric inverse semigroup on a set is the collection of all partial bijections between subsets of with composition as the algebraic operation. We study a minim…
Ideals on countable sets: a survey with questions
Carlos Uzcategui
An ideal on a set is a collection of subsets of closed under the operations of taking finite unions and subsets of its elements. Ideals are a very useful notion in topology…
On the Ellis semigroup of a cascade on a compact metric countable space
Andres Quintero, Carlos Uzcategui
Let be a compact metric countable space, let be a homeomorphism and let be its Ellis semigroup. Among other results we show that the following statements ar…
Selective separability on spaces with an analytic topology
J. Camargo, C. Uzcategui
We study two form of selective selective separability, and , on countable spaces with an analytic topology. We show several Ramsey type properties which imply . For…
Morphologic for knowledge dynamics: revision, fusion, abduction
Isabelle Bloch, Jérôme Lang, Ramón Pino Pérez +1
Several tasks in artificial intelligence require to be able to find models about knowledge dynamics. They include belief revision, fusion and belief merging, and abduction. In this…
