Isotropically Stable De Rham Cohomology

 An isotropically stable initially gauge-invariant De Rham cohomology, often has less of a potential tendency, of spontaneously perturbating out of gauge-invariance, than an isotropically unstable initially gauge-invariant De Rham cohomology, will otherwise have the tendency of being able to spontaneously work to exhibit.TO BE CONTINUED, LATER!
