Manifolds: Pullback/Pushforward Notation

[Michael Jung]

Dear community,

at this stage, the pushforward of a differentiable map '\Phi' is noted by '\Phi^*'.

After some discussion with my collegues and consulting common literature (like "Smooth Manifolds" by Lee), this seems not to be the canonical notation.

I've already opened a ticket for it without considering a discussion in here, before (sorry).

Greetings

Michael
