OBSERVABLES IN GENERAL-RELATIVITY

We emphasize the importance of finding the ''true'' observables of the Einstein theory for canonical quantum gravity. The Hamilton-Jacobi th eory for constrained systems is outlined and its application in terms of Ashtekar variables and Dirac variables is discussed. A specific exa mple of a Bianchi 11 model is solved and the role of one variable as a ''time'' parameter is indicated. We end with a brief remark about an alternative approach
