New Derivation of Off-Shell Representations of the Multi-dimensional Affine and Virasoro Algebras
T. A. Larsson
Algebras of currents and diffeomorphisms in arbitrary dimension have extensions which generalize the affine and Virasoro algebras on the circle. A large class of off-shell represen…
Three Principles for Quantum Gravity
T. A. Larsson
We postulate that the fundamental principles of Quantum Gravity are diffeomorphism symmetry, unitarity, and locality. Local observables are compatible with diffeomorphism symmetry…
Covariant Mickelsson-Faddeev extensions of gauge and diffeomorphism algebras
T. A. Larsson
We construct new extensions of current and diffeomorphism algebras in N>3 dimensions, which are related to the Mickelsson-Faddeev algebra. The result is compatible with Dzhumadil'd…
Quantum Jet Theory, Observer Dependence, and Multi-dimensional Virasoro algebra
T. A. Larsson
We review some key features of Quantum Jet Theory: observer dependence, multi-dimensional Virasoro algebra, and the prediction that spacetime has four dimensions.
QJT as a Regularization: Origin of the New Gauge Anomalies
T. A. Larsson
QJT is considered as a regularization of QFT, where the fields are replaced by finite -jets. The regularized phase space is infinite-dimensional, because not all histories are d…
The physical observer II: Gauge and diff anomalies
T. A. Larsson
In a companion paper we studied field theory in the presence of a physical observer with quantum dynamics. Here we describe the most striking consequence of this assumption: new ga…
