Abstract: We studied the global existence of classical solutions of two-dimensional axisymmetric Euler equations for dusty gas. We derived a group of characteristic decompositions for a two-dimensional axisymmetric Euler system. Using these characteristic decompositions, we determined a sufficient condition for the initial data to ensure the global existence of classical solutions to the Cauchy problem.

Key words: two-dimensional axisymmetric Euler equations, dusty gas, global classical solution, characteristic decomposition
