I wondered if anyone might know of any open access materials, possibly lecture notes, on the content of the following papers or books. P.A.M Dirac, 1950, Can. J. Math. 2,147 "Generalized Hamiltonian Dynamics" P.A.M Dirac, 1933, Proc. Camb. Phil. Soc., 29, 389 "Homogenous variables in classical dynamics" S. Shanmugadhasan, 1963, Proc. Camb. Phil. Soc., 59, 743. H.P.Kunzle, 1969, Ann. Inst. Henri Poincare, 40,107. W. Kundt, 1965, Springer Tracts in Modern Physics, 40,107. A.Mercier, 1963, Canonical Formalism in Classical Mechanics, New York, Dover. P.A.M. Dirac, 1964, Lectures on Quantum Mechanics, Academic Press, London. I have access to the first article mentioned above but would still like lecture notes, problem sets with answers on it's content. Does anyone have any comments on the importance of Dirac's theory? I Googled "dirac generalized hamiltonian" and noted the following were mentioned in the searches returned content. nambu never regular interconnected physical systems, port-hamiltonian hamiltonian structures Dirac solitons Dirac operators recursive properties of Dirac brakets Dirac geometry pontryagin Does anyone have any comments on the importance of "these"?
