Reyes, Enrique G.
On phase spaces and the variational bicomplex (after G. Zuckerman).
(English)
[A] Mladenov, Iva\"ilo M. (ed.) et al., Proceedings of the 5th international conference on geometry, integrability and quantization, Sts. Constantine and Elena, Bulgaria, June 5--12, 2003. Sofia: Bulgarian Academy of Sciences. 189-202 (2004). ISBN 954-84952-8-7/pbk

The construction of phase spaces in field theory is discussed. In particular, following a paper by {\it G. J. Zuckerman} [In: Action principles and global geometry. Mathematical aspects of string theory, Proc. Conf., San Diego/Calif. 1986, Adv. Ser. Math. Phys. 1, 259--284 (1987; Zbl 0669.58014)], the author reviews a Hamiltonian formulation of Lagrangian field theory -- in terms of the variational bicomplex of a fixed trivial fiber bundle [for the definition of this bicomplex, see for example {\it I. M. Anderson}, Introduction to the variational bicomplex. Mathematical aspects of classical field theory, Proc. AMS-IMS-SIAM Jt. Summer Res. Conf., Seattle/WA (USA) 1991, Contemp. Math. 132, 51--73 (1992; Zbl 0772.58013); {\it I. M. Anderson} and {\it N. Kamran}, Acta Appl. Math. 41, 135--144 (1995; Zbl 0848.58043)] -- based on an extension to infinite dimensions of J.-M. Souriau's symplectic approach to mechanics. The problem is how to build phase spaces in a covariant way, using directly the Lagrangian and not going through Dirac's theory of constraints. A basic example is presented.
