Can you take any symplectic 2-form into canonical form via a coordinate transformation?

Physics Asked on February 10, 2021

Let’s say we have a system with Hamilton equations

begin{equation}
dot{Y}^A = Omega^{AB}H_{,B}
end{equation}

where the coordinates are

begin{equation}
Y^A=big(q^i,p_jbig)
end{equation}

where $i=1,dots,N$ and $j=1,dots,N$, $A=1dots, 2N$, $H$ is the Hamiltonian of the system and $Omega$ is a symplectic 2-form, but not the canonical one, which is $Omega_0 = begin{bmatrix}0&mathbb{I}_{Ntimes N}-mathbb{I}_{Ntimes N}&0 end{bmatrix}$

The question is: Can we find new coordinates $Z^A$ (and probably new hamiltonian $K$) such that the equations of motion are written in the canonical form

begin{equation}
dot{Z}^A=Omega_0 ^{AB}K_{,B}
end{equation}

and if so, are there any conditions on $Omega$ for it to happen? Is there a way to obtain such coordinate transformation?
