Contrary to its initial idea, Belnap's (1992) theory of Branching Space-Times (BST) has models in which histories do not resemble re-lativistic space-times or any other physical space-times. The aim of this paper is to define a certain class of BST models, called " Minkows-kian Branching Structures " (MBS), in which histories are isomorphic to Minkowski(More)
There is a remarkable similarity between some mathematical objects used in the Branching Space-Times framework and those appearing in computer science in the fields of event structures for concurrent processing and Chu spaces. This paper introduces the similarities and formulates a few open questions for further research, hoping that both BST theorists and(More)
The region of Volta Grande do Xingu River, in the state of Pará, presents several kinds of land use ranging from extensive cattle farming to agroforestry, and deforestation. Currently, the Belo Monte Hydroelectric Power Plant affects the region. We present a checklist of amphibians and reptiles of the region and discuss information regarding the spatial(More)
