Loop Quantum Cosmology IV : Discrete Time Evolution

  title={Loop Quantum Cosmology IV : Discrete Time Evolution},
  author={Martin Bojowald},
Using general features of recent quantizations of the Hamiltonian constraint in loop quantum gravity and loop quantum cosmology, a dynamical interpretation of the constraint equation as evolution equation is presented. This involves a transformation from the connection to a dreibein representation and the selection of an internal time variable. Due to the discrete nature of geometrical quantities in loop quantum gravity also time turns out to be discrete leading to a difference rather than… CONTINUE READING
