Chart Euclidean smul

EuclideanGroup.chartEuclidean_smul

Plain-language statement

Under the standard chart, the Euclidean action on Space d is the transport of toAffineIsometryMulEquiv acting on EuclideanSpace: chart (g • p) = (toAffineIsometryMulEquiv g) (chart p).

Rotation smul origin

EuclideanGroup.rotation_smul_origin

Project documentation

A rotation fixes the origin: its translation part vanishes (RotationGroup ≤ OriginStabilizer), so ↑r • 0 = 0. Stated in the ↑r form (the simp normal form of r • _, via rotation_smul_eq) so it is a well-formed simp lemma.
