Chas and Sullivan have defined an intersection-type product on the homology of the free loop space LM of an oriented manifold M. In this paper we show how to extend this construction to a topological conformal field theory of degree d. In particular, we get operations on the homology of LM which are parameterized by the homology of the moduli space of open-closed Riemann surfaces.

  1. $b^k$-algebroids and the variety of foliation jets

    math.DG 2025-08 accept novelty 6.0 of 10

    Singular foliations of b^{k+1}-type are equivalent to k-th order foliations and are classified up to isotopy by fundamental group representations into the jet group G_{k,l}, with extension obstructed by a characterist...

  2. Smooth functions that split a Klein bottle into two M\"obius bands

    math.GT 2025-08 conditional novelty 6.0 of 10

    The orbit component of a smooth function on a Klein bottle that splits into two Möbius bands is homotopy equivalent to the product of the orbit components of its restrictions to the two bands.

  3. Graded Frobenius Algebras

    math.AT 2024-12 accept novelty 6.0 of 10

    Graded Frobenius algebras are defined via a graph-based PROP, and an equivalence with explicit map-and-relation descriptions, including all required signs, is proved.
