Minimal regularity solutions of semilinear generalized Tricomi equations

Zhuoping Ruan, Ingo Witt, Huicheng Yin

We prove the local existence and uniqueness of minimal regularity solutions $u$ of the semilinear generalized Tricomi equation ${\partial }_t^{2}u-t^m\Delta u=F(u)$ with initial data $(u(0…
