The paper concerns the study of the Cauchy–Dirichlet problem for a class of hyperbolic second-order operators with double characteristics in presence of transition in a domain of \({\mathbb {R}}^3\). Firstly, we establish some a priori local and global estimates. Then, we obtain some existence results.

一类双曲算子的混合柯西-狄利克雷问题的存在性结果
本文涉及在(\({\ mathbb {R}} ^ 3 \)域中存在转移的情况下,具有双重特征的一类双曲型二阶算符的Cauchy-Dirichlet问题的研究。首先,我们建立一些先验的局部和全局估计。然后,我们获得一些存在结果。
