Some Comments on Categories, Particles and Interactions
  An algebraic formalism for the study of interacting particle systems is developed. Particle processes are described in terms of the category theory. The problem for the unique description of these processes is discussed. Categories relevant for this subject are described. The concept of generalized transmutations of interacting particle systems is considered. The connection with a system with some generalized statistics is explained.
