My Name is Vincent Levorato, and I am Researcher & Teacher in Computer Sciences

I am a doctor in Computer Sciences who is mainly interested in Complex Systems Modeling, and Complex Networks such as:
    - social networks, mobile networks
    - communities detection
    - diffusion models
    - multi-agent systems
I am also doing some research in machine learning, and computation models fields. Since September 2011, I am working at the CESI company in the IRISE institute, and I am also an associate researcher in the LIFO laboratory (Graphs, Algorithms and Models of Computation team). Concerning education, I am a teacher at exia.cesi computer sciences school, and national responsible for Research and Sciences.
I received my PhD in Computer Sciences in 2008 from University Paris Vincennes-St Denis at the EPHE-Sorbonne LaISC laboratory after making my previous formation at University of Reims (Fr).

Z.T. Belmandt. Basics of Pretopology, Hermann, 155 pages, ISBN : 978 27056 8077, 2011

Z.T. Belmandt is a collective name for a group of scientists working on Pretopology namely Marcel Brissaud, Michel Lamure, Jean-Jacques Milan, Jean Paul Auray, Nicolas Nicoloyannis, Gérard Duru, Michel Terrenoire, Daniel Tounissoux, Djamel Zighed, Stéphane Bonnevay, Le Thanh Van, Marc Bui, Soufian Ben Amor and Vincent Levorato.
Pretopology theory relies on the statement that the axiomatic of mathematical topology is too strong to model the phenomena of social sciences. This axiomatic has to be reconsidered to give birth to a theory that is adapted to data issued from these fields of expertise, better than trying to force data to fit to an existing and inadequate theory. This book is the first English revised version of a first book, published in French, which is planned to be the first of a series dedicated to the whole set of results obtained in Pretopology: continuity, connectedness, associated metric... Many applications of Pretopology were conducted in various fields: economy with the structural analysis of a economy, game theory with the study of the dynamics of coalitions in cooperative games, sociology with analysis of social networks, data analysis with the construction of clustering algorithms, pattern recognition with digital image analysis as in mathematical morphology, etc.
