# Reference: Finsler Derivative?

On the wikipedia page "Generalizations of derivative" the author mentions: " in Finsler geometry, one studies spaces which look locally like Banach spaces. Thus one might want a derivative with some of the features of a functional derivative and the covariant derivative."

My question is what does this derivative look like, explicity (for a Finsler manifold over a general Banach space)?

Can someone provide a reference also, much appreciated.

• a nonlinear connection that defines the covariant derivative in Finsler geometry is here --- is this what you want? – Carlo Beenakker Nov 4 '15 at 5:23
