The renormalisation group equation for N -point correlation functions can be interpreted in a geometrical manner as an equation for Lie transport of amplitudes in the space of couplings. The vector field generating the diffeomorphism has components given by the βfunctions of the theory. It is argued that this simple picture requires modification whenever any one of the points at which the ampli...

A deformation of the wave equation on a two-dimensional black hole is considered as a toy-model for possible gravitational or stringy nonlocal effects. The deformed wave-equation allows for an initial-value problem despite being nonlocal. The singularity present in the classical geometry is resolved by the deformation, so that propagation of a wave-packet can be continued through the classicall...

We consider dyon configurations in the standard electroweak model. In the presence of a θ term and no fermions, the usual result q = (n+ θ/2π)e is obtained for the electric charge spectrum. The effect of including standard model fermions is discussed qualitatively.
