Detection of homotopy classes in complex projective space.
Abstract
This paper investigates how the geometry of a cycle in the loop space of a Riemannian manifold controls its topology. For fixed one can ask how large can be for cycles supported in loops of length and of volume for a suitably defined notion of volume of in loop space. We show that an upper bound to this question provides upper bounds Gromov's distortion of higher homotopy groups. We also show that we can exhibit better lower bounds than are currently known for the corresponding questions for Gromov's distortion. Specifically, we show there exists a detecting the homotopy class of the puncture in and a family of cycles with the geometric bounds above such that .
