Diagrams of Noncommutative Φ Theory from String Theory

Starting from tree and one-loop tachyon amplitudes of open string theory in the presence of a constant B-field, we explore two problems. First we show that in the noncommutative field theory limit the amplitudes reduce to tree and one-loop diagrams of the noncommutative Φ theory. Next, we check factorization of the one-loop amplitudes in the long cylinder limit. PACS : 11.25.-w, 11.25.Db

Noncommutative Geometry from String Theory: Annulus Corrections

We develop a method in which it is possible to calculate one loop corrections to the noncommutativity parameter found for open strings in a background Fμν field. We first reproduce the well known disk results for θ μν . We then consider the case of charged and neutral open strings on the brane, and show in both cases that the result is the same as in the disk case, apart from a multiplicative f...

DEVELOPMENT IN STRING THEORY

The string theory is a fast moving subject, both physics wise and in the respect of mathematics. In order to keep up with the discipline it is important to move with new ideas which are being stressed. Here I wish to give extracts from new papers of ideas which I have recently found interesting. There are six papers which are involved: I ."Strings formulated directly in 4 dimensions " A. N...

Category Theory Using String Diagrams

In [Fokkinga, 1992a], [Fokkinga, 1992b] and [Fokkinga and Meertens, 1994] a calculational approach to category theory is developed. The scheme has many merits, but sacrifices useful type information in the move to an equational style of reasoning. By contrast, traditional proofs by diagram pasting retain the vital type information, but poorly express the reasoning and development of categorical...

String diagrams for game theory

This paper presents a monoidal category whose morphisms are games (in the sense of game theory, not game semantics) and an associated diagrammatic language. The two basic operations of a monoidal category, namely categorical composition and tensor product, correspond roughly to sequential and simultaneous composition of games. This leads to a compositional theory in which we can reason about pr...
