The existence of instantons implies non-trivial spacetime topology and cohomology
the verdict
SUPPORTED
the evidence backs this
confidence 80/100
The presence of instantons in gauge theories and gravity is deeply connected to non-trivial topological properties and cohomology, as seen through characteristic classes and twistor formulations.
