Classical and quantum geometry of moduli spaces in three-dimensional gravity
J. E. Nelson, R. F. Picken
We describe some results concerning the phase space of 3-dimensional Einstein gravity when space is a torus and with negative cosmological constant. The approach uses the holonomy…

Some Applications of the ADM Formalism
J. E. Nelson
The ADM Formalism is discussed in the context of 2+1--dimensional gravity, uniting two areas of relativity theory in which Stanley Deser has been particularly active. For spacetime…

Quantum Matrix Pairs
J. E. Nelson, R. F. Picken
The notion of quantum matrix pairs is defined. These are pairs of matrices with non-commuting entries, which have the same pattern of internal relations, q-commute with each other…
