DOES LOOP QUANTUM-GRAVITY IMPLY LAMBDA=0

We suggest that in a recently proposed framework for quantum gravity, where Vassiliev invariants span the the space of states, the latter is dramatically reduced if one has a non-vanishing cosmological constant . This naturally suggests that the initial state of the universe shoul d have been one with Lambda = 0. (C) 1998 Elsevier Science B.V. All ri ghts reserved.
