Geometric Degree of Non Conservativeness

Symplectic structure is powerful especially when it is applied to Hamiltonian systems.We show here how this symplectic structure may de ne and evaluate an integer index that measures the defect for the system to be Hamiltonian. This defect is called the Geometric Degree of Non Conservativeness of the system. Darboux theorem on di erential forms is the key result. Linear and non linear frameworks are investigated.
