We propose and support the possibility that the shape of topological density2-point function in pure-glue QCD is crucially, and possibly entirely,determined by the space-time folding (geometry) of the double-sheetsign-coherent structure of Ref.[1], while the distribution of topologicaldensity within individual sheets only determines the overall magnitude of thecorrelator at finite physical distances. A specific manifestation of this,discussed here, is that the shape of the correlation function (encoding e.g.the masses of pseudoscalar glueballs) is reproduced upon the replacement q(x)-> sgn(q(x)), i.e. by considering the double sheet of the same space-timegeometry but with constant magnitude of topological density. Combined withprevious results on the fundamental topological structure, this suggests that acollective degree of freedom describing topological fluctuations of QCD vacuumcan be viewed as a global space-filling homogeneous double membrane. Selectedpossibilities for practical uses of this are discussed.
