Abstract

We study a variant of the embedding functor Emb(M,N)\mathop{\mathrm{Emb}}(M, N) that incorporates homotopical data from the frame bundle of the target manifold NN. Given a parallelized mm-manifold MM and an nn-manifold NN equipped with a section of its mm-frame bundle, we define a modified embedding functor Emb~(M,N)\widetilde{\mathop{\mathrm{Emb}}}(M, N) that interpolates between the standard embedding and a reference framing. Using the manifold calculus of functors, we identify the Taylor tower of Emb~(M,N)\widetilde{\mathop{\mathrm{Emb}}}(M, N) with a mapping space of right modules over the Fulton-MacPherson operad. We prove a convergence theorem under a codimension condition, establishing a weak equivalence between Emb~(M,N)\widetilde{\mathop{\mathrm{Emb}}}(M, N) and its Taylor approximation. Finally, under rationalization, we describe the derived mapping space in terms of a combinatorial hairy graph complex, enabling computational access to the rational homotopy type of the space of embeddings.
