On the algebraic structure of the holomorphic anomaly for \(\widehat {c}=3\) topological strings
The present paper is based on the lecture given by the author at the ``Fifth International Conference on Mathematical Physics, String Theory and Quantum Gravity'' held in Alushta from June 10-20, 1994. The author proposes to understand the holomorphic anomaly in terms of a contact term algebra that fuses the topological and antitopological sectors, and in which the dilaton is included in a natural way.
