A Compactification of the Real Configuration Space as an Operadic Completion
Abstract
S. Axelrod and I.M. Singer constructed a compactification of the configuration space of distinct points in a Riemannian manifold V. A similar compactification for the moduli space of configurations of distinct points in the plane (mod the affine group action) was considered by E. Getzler and J.D.S. Jones. They observed that this compactification carries a natural structure of an operad. In the present note we show that (noncompactified) configuration spaces form a partial operad (or a partial module over a partial operad) and that the compactification can be described as an operadic (or modular) completion. This approach immediately gives the operad (or module) structure on the compactification. We also discuss the spectral sequence of the stratification and identify the second term of this spectral sequence to the bar resolution of an operadic module. Our results generalize the work of Getzler, Kimura, Jones, Stasheff, Voronov and others to the case of configurations in a general Riemannian manifold.
