Euler-Poincare equations with constraints
I guess so. The use of a Finsler metric and linear constraints wont change things. The lagrangian in the above equation is arbitrary. The use of affine constraints does change the equations (not sure how to write it though). However, "linear" is a special case of "affine", so the argument should still work. |

Construction of the Lie functor: left vs. right invariant vector fields on Lie groups and Lie groupoids
Perhaps the answer to (2) is "yes". I get the impression from books by Jerry Marsden on mechannics that much of Lie's work was motivated by studying the Rigid body. Here the phase space ends up being the left invariant vector-fields, and this may have motivated Lie's convention. Just a guess, so I'm hesitant to post it as an answer. |

Does every compact manifold exhibit an almost global chart
Thank you for the reference Igor. I was unaware of the nowhere dense property. |

Explicit form for hermitian structure $h$ with respect to $\omega$
Sorry, I am not familiar with the notation. Is $\frac{i}{2} \partial \bar{\partial} \equiv \frac{i}{2} \Delta$? Also, what is $lnh$ vs $h$? |

Authorship, and order of authors
This situation arises frequently when doing interdisciplinary research. I'm early in my career, and I've decided to be a bit more aggressive when I do 85% of the work by asking that I be first author. I don't know who on a hiring committee will read my CV, but often it will not be a mathematician. |

Cotangent bundle lift theorem
If $G:T^*M \to T^*M$ is a fiber map over the identity when $\pi \circ G = \pi$. I think you wrote $dG \circ d\pi = d\pi$ when you meant to write $d\pi \circ dG = d\pi$. Also a parenthesis was missing. |
