On semilinear Tricomi equations in one space dimension
Daoyin He, Ingo Witt, Huicheng Yin
For 1-D semilinear Tricomi equation with initial data , where , , $p>…
Blowup of classical solutions for a class of 3-D quasilinear wave equations with small initial data
Bingbing Ding, Ingo Witt, Huicheng Yin
This paper is concerned with the small smooth data problem for the 3-D nonlinear wave equation $\partial_t^2u-\left (1+u+\p_t u\right)Δu=0$. This equation is prototypical of the mo…
On the existence and cusp singularity of solutions to semilinear generalized Tricomi equations with discontinuous initial data
Zhuoping Ruan, Ingo Witt, Huicheng Yin
In this paper, we are concerned with the local existence and singularity structure of low regularity solutions to the semilinear generalized Tricomi equation $\p_t^2u-t^mΔu=f(t,x,u…
On the lifespan of and the blowup mechanism for smooth solutions to a class of 2-D nonlinear wave equations with small initial data
Bingbing Ding, Ingo Witt, Huicheng Yin
This paper is concerned with the lifespan and the blowup mechanism for smooth solutions to the 2-D nonlinear wave equation $\p_t^2u-\ds\sum_{i=1}^2\p_i(c_i^2(u)\p_iu)$ , where…
