报告简介：

Herbert S. Green introduced a generalised quantisation in 1953, which gave rise to the celebrated parastatistics that included the standard Bose-Fermi statistics as the special case of order 1. In recent years there have been reports of quantum simulations of para-particles using systems of trapped ions, indicating that some quasi particles observed in condensed matter may indeed be parabosons or parafermions.

Parastatistics has been widely studied mathematically since its inception. However, the following fundamental questions concerning parafermions have not been addressed systematically:

(1) What are the algebras in which the coordinates of parafermions at the classical level are valued in?

(2) What are the spaces whose functions describe classical parafermionic fields?

It is well known that these questions were answered for order 1 parafermions (i.e., usual fermions) by the theory of supermanifolds built with Grassmann algebras.  We generalise the theory to answer the above questions for parafermions of orders greater than 1.
