Canonical transformations in the covariant phase space formalism
Ref. 1 is talking about the Peierls bracket in the Lagrangian formalism. It is equivalent to the presymplectic structure in the covariant Hamiltonian formalism, cf. e.g. section 4.1 in Ref. 3.
Ref. 1 ...

Commutation of the Hamiltonian with the generator of boost
...From the above, we see that $$\{M^{0i}, H\} = P^i$$
No, you should have:
$$
\{M^{0i}, H\} = -P^i
$$
...Why is it that $\frac{d}{dt}M^{0i}\neq \{H, M^{0i}\}$? Can someone please explain?
It's ...
