    Operads, configuration spaces and quantization

    We review several well-known operads of compactified configuration spaces and construct several new such operads, C, in the category of smooth manifolds with corners whose complexes of fundamental chains give us (i) the 2-coloured operad of A-infinity algebras and their homotopy morphisms, (ii) the 2-coloured operad of L-infinity algebras and their homotopy morphisms, and (iii) the 4-coloured operad of open-closed homotopy algebras and their homotopy morphisms. Two gadgets - a (coloured) operad of Feynman graphs and a de Rham field theory on C - are introduced and used to construct quantized representations of the (fundamental) chain operad of C which are given by Feynman type sums over graphs and depend on choices of propagators.Comment: 58 page

    The extended moduli space of special Lagrangian submanifolds

    Full text link
    It is well known that the moduli space of all deformations of a compact special Lagrangian submanifold XX in a Calabi-Yau manifold YY within the class of special Lagrangian submanifolds is isomorphic to the first de Rham cohomology group of XX. Reinterpreting the embedding data X⊂YX\subset Y within the mathematical framework of the Batalin-Vilkovisky quantization, we find a natural deformation problem which extends the above moduli space to the full de Rham cohomology group of XX.Comment: 15pages.
