,[7] From the point of view of the constraint algorithm, the homogeneous case is trivial because E ≡ 0 (see section III).

,[10] Throughout this paper, we assume for simplicity that all physical systems under consideration are time-independent and that all relevant phasespaces are finite-dimensional; however, all of the theory developed in this paper can be applied when these restrictions are removed with little or no modification. For details concerning the infinite-dimensional case, see refs. [5] and [18].

,[12] We herein establish some notation and terminology. All manifolds and maps appearing in this paper are assumed to be C∞. We designate the natural pairing TM x T*M → R by <|>. The symbol i denotes the interior product. Note that if γ is a p-form, and X1, ..., Xp are vectorfields, then i(X1) ... i(Xp)γ = γ(Xp, ... , X1). The symbol « | N » means « restriction to the submanifold N ». If j : N → M is the inclusion, then we denote by γ | N the restriction of γ to N. Given a 2-form Ω on M, we define the « Ω-orthogonal complement » of TN in TM to be TN1 = {Z∈TM such that Ω(Z, Y) = 0 for all Y∈TN}. Furthermore, we define ker Ω = {Y∈TM such that i(Y)Ω = 0 }. If f : M → P is smooth, then we denote by T f or f* the derived mapping TM → TP. We have ker T f = { Y∈TM such that T f(Y) = 0 } .

[13] For another definition of FL (which is logically independent of the almost tangent structure J), see ref. [1].

,[15] We assume that all of the Pl appearing in the algorithm are in fact imbedded submanifolds. Otherwise, one must resort to standard tricks, e. g., work locally where everything is manageable (see Section IV).

[16] In fact, there does not even exist a unique local Hamiltonian formalism corresponding to such a Lagrangian system, as, e. g., with L = 1/4v4 - 1/2v2 .

[17] In the following, TM1/1 denotes the ω1-orthogonal complement (see [12]).
