Number Field Finite Adele Ring is Central Simple add Haar Scalar Factor left mul eq right mul

NumberField.FiniteAdeleRing.isCentralSimple_addHaarScalarFactor_left_mul_eq_right_mul

Plain-language statement

left multiplication and right multiplication by a unit have the same Haar character on B ⊗ 𝔸_K^f. See also NumberField.FiniteAdeleRing.tensor_isCentralSimple_addHaarScalarFactor_left_mul_eq_right_mul which proves it for 𝔸_K^f ⊗ B.
