A universal minimal spinor set of linear differential equations describing anyons and ordinary integer and half-integer spin fields is constructed with the help of deformed Heisenberg algebra with reflection. The construction is generalized to some d = 2 + 1 supersymmetric field systems. Quadratic and linear forms of action functionals are found for the universal minimal as well as for supersym...

Comparable Fora

As the title suggests, our paper deals with web discussion fora, whose content can be considered to be a special type of comparable corpora. We discuss the potential of this vast amount of data available now on the World Wide Web nearly for every language, regarding both general and common topics as well as the most obscure and specific ones. To illustrate our ideas, we propose a case study of ...

The zero-temperature Glauber dynamics is used to investigate the persistence probability P (t) in the Potts model with Q = 3, 4, 5, 7, 9, 12, 24, 64, 128, 256, 512, 1024, 4096, 16384,..., 230 states on directed and undirected Barabási-Albert networks and Erdös-Rényi random graphs. In this model it is found that P (t) decays exponentially to zero in short times for directed and undirected ErdösR...
