How to Invent Functions
The paper presents the abstraction transformation which is a fundamental method for creating functions in ADATE. The use of abstraction turns out to be similar to evolution by gene duplication which is emerging as the most important theory of \building blocks" in natural genomes. We discuss the relationship between abstraction and its natural counterparts, but also give novel technical details ...
متن کاملNote on N = 0 string as N = 1 string
A similarity transformation, which brings a particular class of the N = 1 string to the N = 0 one, is explicitly constructed. It enables us to give a simple proof for the argument recently proposed by Berkovits and Vafa. The N = 1 BRST operator is turned into the direct sum of the corresponding N = 0 BRST operator and that for an additional topological sector. As a result, the physical spectrum...
متن کاملThe N = 2 Open String
We show that the N = 2 open string describes a theory of self-dual Yang Mills (SDYM) in (2, 2) dimensions. The coupling to the closed sector is described by SDYM in a Kähler background, with the Yang-Mills fields providing a source term to the self-duality equation in the gravity sector. The four-point S-matrix elements of the theory vanish, so the tree-level unitarity constraints leading to th...
متن کاملN-string vertices in string field theory.
We give the general form of the vertex corresponding to the interaction of an arbitrary number of strings. The technique employed relies on the “comma” representation of String Field Theory where string fields and interactions are represented as matrices and operations between them such as multiplication and trace. The general formulation presented here shows that the interaction vertex of N st...
متن کاملN=4 string is the same as the N=2 string.
We redo the quantization of the N=4 string, taking into account the reducibility of the constraints. The result is equivalent to the N=2 string, with critical dimension D=4 and signature (++−−). The N=4 formulation has several advantages: the σ-model field equations are implied classically, rather than by quantum/β-function calculations; self-duality/chirality is one of the super-Virasoro const...
