Parafermi Field Theory

Parabose – Parafermi Supersymmetry

The (p = 2) parabose – parafermi supersymmetry is studied in general terms. It is shown that the algebraic structure of the (p = 2) parastatistical dynamical variables allows for (symmetry) transformations which mix the parabose and parafermi coordinate variables. The example of a simple parabose – parafermi oscillator is discussed and its symmetries investigated. It turns out that this oscilla...

Field Theory

In the meeting of this year, there were a total of 165 contributions in the form of panel and oral sections, besides two plenary and three parallel talks. As occurred in the previous meetings, these talks refer to recent and/or signi cative subjects in the Field Theory. At this year, one talk was on the Anti-de Sitter (AdS){ Conformal Field Theory (CFT) correspondence, two on nonconcommutative ...

Operads and Conformal Field Theory Lecture 1: Conformal Field Theory

Physicists have developed very advanced methods to compute such integrals. For example, the famous Feynman diagram technique allows us to compute the above integral for a rather particular function S(x), a small perturbation of a positive de nite quadratic form in R . Sometimes, elaborate techniques of physicists to compute simple things nd an amazing application to very general things in mathe...

D-brane effective field theory from string field theory

Open string field theory is considered as a tool for deriving the effective action for the massless or tachyonic fields living on D-branes. Some simple calculations are performed in open bosonic string field theory which validate this approach. The level truncation method is used to calculate successive approximations to the quartic terms φ4, (AAμ) 2 and [Aμ, Aν ] 2 for the zero momentum tachyo...
