Fractal statistics, fractal index and fractons
The concept of fractal index is introduced in connection with the idea of
universal class of particles or quasiparticles, termed fractons, which obey
fractal statistics. We show the relation between fractons and conformal field
theory(CFT)-quasiparticles taking into account the central charge and
the particle-hole duality , for
integer-value of the statistical parameter. The Hausdorff dimension
which labelled the universal classes of particles and the conformal anomaly are
therefore related. We also establish a connection between Rogers dilogarithm
function, Farey series of rational numbers and the Hausdorff dimension.Comment: Latex, 7 pages, references update, To appear Proceedings Workshop on

A quantum-geometrical description of fracton statistics
We consider the fractal characteristic of the quantum mechanical paths and we
obtain for any universal class of fractons labeled by the Hausdorff dimension
defined within the interval 1, a fractal
distribution function associated with a fractal von Neumann entropy. Fractons
are charge-flux systems defined in two-dimensional multiply connected space and
they carry rational or irrational values of spin. This formulation can be
considered in the context of the fractional quantum Hall effect-FQHE and number
theory.Comment: Typos corrected, latex, 8 pages, Talk given at the 2nd International
