On the problem of time in two and four dimensions
T. A. Larsson
In general-covariant theories the Hamiltonian is a constraint, and hence there is no time evolution; this is the problem of time. In the subcritical free string, the Hamiltonian ce…
Manifestly covariant canonical quantization III: Gravity, locality, and diffeomorphism anomalies in four dimensions
T. A. Larsson
The recently introduced manifestly covariant canonical quantization scheme is applied to gravity. New diffeomorphism anomalies generating a multi-dimensional generalization of the…
Why the Mickelsson-Faddeev algebra lacks unitary representations
T. A. Larsson
A simple plausibility argument is given.
Manifestly covariant canonical quantization II: Gauge theory and anomalies
T. A. Larsson
In hep-th/0411028 a new manifestly covariant canonical quantization method was developed. The idea is to quantize in the phase space of arbitrary histories first, and impose dynami…
Manifestly covariant canonical quantization I: the free scalar field
T. A. Larsson
Classical physics is reformulated as a constrained Hamiltonian system in the history phase space. Dynamics, i.e. the Euler-Lagrange equations, play the role of first-class constrai…
A diffeomorphism anomaly in every dimension
T. A. Larsson
Field-theoretic pure gravitational anomalies only exist in dimensions. However, canonical quantization of non-field-theoretic systems may give rise to diffeomorphism anomali…
