We consider an instructive toy model of the gauge-string dualities which exist between quantum field theory and theories of quantum gravity. In this example we study the Gaussian matrix model as our gauge theory and the topological A-model string theory on P ^1 as our theory of quantum gravity.
We propose operators in the matrix model that are dual to the gravitational descendants of the puncture operators of the topological string theory. We test our proposal by showing that matrix model correlators obtained from the recursion relations that follows from a systematic 1/N expansion
of well chosen Schwinger-Dyson equations are in complete agreement with correlators in the dual
topological string theory, up to contact terms.
