loop space (original) (raw)
Let X be a topological space, and give the space of continuous maps [0,1]→X, the compact-open topology
, that is a subbasis for the topology is the collection of sets {σ:σ(K)⊂U} for K⊂[0,1] compact
and U⊂X open.
Then for x∈X, let ΩxX be the subset of loops based at x (that is σ such that σ(0)=σ(1)=x), with the relative topology.
