Substitution of the old variable to a generating function
Assume that we have one of the 4 types of generating functions (say F(p, Q)) which defines a symplectomorphism $T$:
$(P,Q) = (u(p,q), v(p,q))$. Now we can make a substitution and get a function $G(p,q)...

What is the relation between the different generating functions thought as finite approximations of action functionals
In the book Introduction to symplectic topology by MC Duff and Salamon, a discrete analogue of the action functional is defined on $\mathbb{R}^{2n}$. The idea is that a Hamiltonian isotopy can be ...
