RST 2011  Milano, September 14-16


The RST workshops are devoted to state-of-the-art scientific results about rough sets from a theoretical standpoint. Great importance is attached to informal discussion among participants. A round table concerning foundational and open problems in rough sets theory is included in each workshop.

The third RST workshop will be held at Milano-Bicocca University, Milano, Italy, September 14-16, 2011. This edition will devote special attention to potential relationships between rough sets, on the one hand, and many-valued logic and belief functions, on the other hand. Therefore, the programme committe especially encourages submissions that focus on such relationships.

The scientific programme will consist of three full-length invited talks, a number of shorter contributed talks, a tutorial, and a round table.

Invited Speakers

Thierry Denoeux, Theory of belief functions: introduction, recent advances and connections with rough set theory

Antonio Di Nola, Finite valued MV-algebras: generalities and dualities

Ewa Orlowska, Discrete representation and duality in theories of approximate reasoning


Piero Pagliani will give a tutorial on “The polymorphic logic of Rough Set Systems”


Participants interested in delivering a contributed talk should submit an extended abstract (2-4 pages) via the Easy Chair web page at
