摘要
We obtain the Hausdorff dimension, h = 2 - 2s, for particles with fractional spins in the interval, 0 < s < 0.5, such that the manifold is characterized by a topological invariant given by, W = h + 2s - 2p. This object is related to fractal properties of the path swept out by fractional spin particles, the spin of these particles, and the genus (number of anyons) of the manifold. We prove that the anyonic propagator can be put into a path integral representation which gives us a continuous family of Lagrangians in a convenient gauge. The formulas for, h and W, were obtained taking into account the anyon model as a particle-flux system and by a qualitative inference of the topology.
