A proof of the Dirac conjecture for a class of finite-dimensional Hamilton-Dirac systems.
This paper is devoted to constrained Hamiltonian systems. By definition constraints in a neighborhood of a point \(x_0\in \mathbb{E}\) is a map \(\phi: \mathbb{E}\to\mathbb{E}_\phi\) satisfying the following conditions: a) \(\phi\) is continuously differentiable in a neighborhood of the point \(x_0\) and \(\phi(x_0)= 0\); b) the map \(\phi'(x_0): \mathbb{E}\to \mathbb{E}_\phi\) is surjective. Here \(\mathbb{E}\), \(\mathbb{E}_\phi\) are the Euclidean spaces. A Dirac Hamiltonian system on the phase space \(\mathbb{E}\) is a set \((H,\phi,\mathbb{E}, I)\), where \(H\in C^\infty(\mathbb{E}, R^1)\), \(\phi: \mathbb{E}\to \mathbb{E}_\phi\) is a constraint, \(\mathbb{E}\) is an even-dimensional Euclidean space, and \(I: \mathbb{E}\to \mathbb{E}\) is a symplectic operator. The author introduces the Dirac class, and within this class proves the classical Dirac conjecture. The proof is based on the theory of control systems.
