Pole INRIA project-team $\pi r^2$ Thematic team Algebra and computation Thematic team Analysis and conception of systems Thematic team Proofs and programs Proofs, programs and systems Leader Yves Guiraud Research themes The pole Proofs, programs and systems (PPS) aims at advancing the state of the art in the fields of theoretical foundations of programming languages, of interactive proof assistants, and more generally of computational formalisms. We investigate these subjects by combining three different approaches: a syntactic approach, developing theoretical languages based on logical formalisms, an algebraic approach, studying the mathematical structures underlying computation, a practical approach, modeling and analyzing actual computational systems. The pole is structured into three thematic teams, according to the three different approaches. These teams use their specific methods to contribute to the common scientific goals: Proofs & Programs Syntax and types Proof theory Algebra & Computation Denotational semantics Categories and homotopy Combinatorial algebra and rewriting Analysis & Conception of Systems The Coq proof assistant Linear rewriting Concurrent and probabilistic systems Programming languages Software components The Babel routing protocol The PPS pole hosts the project-team $\pi r^2$ which is joined between INRIA, CNRS and Université Paris-Diderot — Paris 7. We also host several members of IRILL, the Center for Research and Innovation on Free Software which is a joined structure of INRIA, Université Paris-Diderot — Paris 7 and Université Pierre-et-Marie-Curie — Paris 6.
