View on Github →chore(Analysis/Calculus/VectorField): fix order of V and W in fderiv_apply_lieBracket lemmas (#45860)
The docstrings of four lemmas described the "derivative along [W, V] as the commutator of the derivatives along W and V". In fact, the lemmas were about the commutator [V, W].
This have been due to the order of hypotheses (first hW, then hV) - which is inconsistent with the order of arguments (first V, then W): re-order the hypotheses to put hV first.
Breaking change: re-order the first two arguments passed to fderiv_apply_lieBracket and friends.
