On the global solution problem for semilinear generalized Tricomi equations, I

Daoyin He, Ingo Witt, Huicheng Yin

In this paper, we are concerned with the global Cauchy problem for the semilinear generalized Tricomi equation ${\partial }_t^{2}u-t^m\Delta u=|u{|}^p$ with initial data $(u(0,\cdot), \partia…
