IsTopologicallyNilpotent.mul_left_of_commute

∀ {R : Type u_1} [inst : TopologicalSpace R] [inst_1 : Ring R] [IsLinearTopology R R] {a b : R},
  IsTopologicallyNilpotent b → Commute a b → IsTopologicallyNilpotent (a * b)

If a and b commute and b is topologically nilpotent, then a * b is topologically nilpotent.
