Abstract

We study the structures of partition functions of the large $N$ generalized two-dimensional Yang-Mills theories ( $g Y M_{2}$ ) by recasting the higher Casimirs. We clarify the appropriate interpretations of them and try to extend the Cordes-Moore-Ramgoolam's topological string model describing the ordinary $Y M_{2}$ \cite{CMR} to those describing $g Y M_{2}$ . We present the expressions of the appropriate operators to reproduce the higher Casimir terms in $g Y M_{2}$ . The concept of ''deformed gravitational descendants'' will be introduced for this purpose.
