Witten's Cubic Vertex in the Comma Theory (I)
A. Abdurrahman, J. Bordes
In is shown explicitly that the Witten's interaction 3-vertex is a solution to the comma overlap equations; hence establishing the equivalence between the conventional and the "com…
Operator approach to the Gluing Theorem in String Field Theory
Abdulmajeed Abdurrahman, Jose Bordes, Cristobal Lara
An algebraic proof of the Gluing Theorem at tree level of perturbation theory in String Field Theory is given. Some applications of the theorem to closed string non-polynomial acti…
N-String Vertices in String Field Theory
J. Bordes, A. Abdurrahman, F. Anton
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 Fi…
Half-String Approach to Closed String Field Theory
F. Anton, A. Abdurrahman, J. Bordes
In this letter we present an operator formalism for Closed String Field Theory based on closed half-strings. Our results indicate that the restricted polyhedra of the classical non…
