HILBERT-SPACE AND STRUCTURE CONSTANTS OF DESCENDANT FIELDS IN 2-DIMENSIONAL CONFORMAL THEORIES

We have developed an algorithm to compute the Hilbert-space basis and the operator algebra of descendant fields for (1 + 1)-dimensional conformal field theories. Implemented as a Mathematica computer program, this algorithm is used to obtain nonperturbatively the spectrum of the transfer matrix theories, seen as deformations of a massless conformal theory.
