There is a problem with this file, that we have a diamond: complex numbers already have a measure space instance before the start of the file (you can try |
Indeed, this is discussed here |

I see, so the plan is to remove the instance at the start of the file (then the Haar measure instance is synthesised automatically) and just come up with a new proof of |

We prove some lemmas that will be useful in following PRs #6832 and #7037, mainly: ```lean theorem Basis.addHaar_eq {b : Basis ι ℝ E} {b' : Basis ι' ℝ E} : b.addHaar = b'.addHaar ↔ b.addHaar b'.parallelepiped = 1 theorem Basis.parallelepiped_eq_map (b : Basis ι ℝ E) : b.parallelepiped = (TopologicalSpace.PositiveCompacts.piIcc01 ι).map b.equivFun.symm b.equivFunL.symm.continuous theorem Basis.addHaar_map (b : Basis ι ℝ E) (f : E ≃L[ℝ] F) : map f b.addHaar = (b.map f.toLinearEquiv).addHaar ``` Co-authored-by: Eric Wieser <[email protected]>

We remove the instance ```lean instance measureSpace : MeasureSpace ℂ := ⟨Measure.map basisOneI.equivFun.symm volume⟩ ``` in `MeasureTheory.Measure.Lebesgue.Complex` since `ℂ` has already a `measureSpace` instance coming from its `InnerProductSpace` structure over `ℝ`, and fix the proof of `volume_preserving_equiv_pi`.
