What are Hamilton's equations with respect to a nonstandard symplectic form?
A Hamiltonian $H:M\rightarrow \mathbb{R}$ defines a vector field $X_H$ through the equation
\begin{equation}
\omega(X_H,\cdot)=dH.
\end{equation}
For $\omega=F(q,p)dq\wedge dp$ and substituting the …

Rigorous definition of the variation
A definition can be given by direct generalization of the one on the question. Take the space of fields to be the space $C^\infty(X, M)$ of smooth functions between two manifolds. For any smooth funct …
