In this paper, we are concerned with the global Cauchy problem for the semilinear generalized Tricomi equationwith initial data, where,(),,, and(). We show that there exists a critical exponentsuch that the solutionu, in general, blows up in finite time when. We further show that there exists a conformal exponentsuch that the solutionuexists globally whenprovided that the initial data is small enough. In case, we will establish global existence of small data solutionsuin a subsequent paper (He et al. 2015).
