Web8 aug. 2024 · If you look at the photos I posted you can actually see the clean area where the brushes were in contact. As per Kevins post about corrosion causing an open circuit the picture is of a pump that was open circuit. Cleaning just the commutator meant the pump was no longer open circuit and worked fine after cleaning. Of course it was then useless. Web(G;N)-commutator lengths. Here for x 2[G;N], the (G;N)-commutator length cl G;N(x) of x is the minimum number n such that x is a product of n commutators which are written as …

WebWe prove that for any euclidean ring R and n ≥ 6, Γ = SL n (R) has no unbounded quasi-homomorphisms. By Bavard’s duality theorem, this means that the stable commutator length vanishes on Γ. The result is particularly interesting for R = F[x] for a certain field F (such as ℂ), because in this case the commutator length on Γ is known to be unbounded.
