摘要
We derive dispersionless Hirota equations for the extended dispersionless Toda hierarchy. We show that the dispersionless Hirota equations are just a direct consequence of the genus-zero topological recurrence relation for the topological a%26quot;,P-1 model. Using the dispersionless Hirota equations, we compute the twopoint functions and express the result in terms of Catalan numbers.
