摘要： 考虑在动态边界条件下,
非线性~$p$($x$)-Kirchhoff~方程组解的非全局存在性,
该方程组带有非线性外力项~$Q$~和非线性源项$~f$.
通过研究方程组解的自然能量, 证明在初始能量小于一个临界值时,
方程组解的非全局存在性.
并将带有拟线性齐次~$p$-拉普拉斯算子的~$p$-Kirchhoff~方程组推广到~$p(x)$-Kirchhoff~方程组,
该方程组近年被用来模拟很多现象.

关键词: p(x)$-Kirchhoff~方程组, 非全局存在性, 非线性源项和外力项

Abstract: This paper considered the global non-existence of solutions
of nonlinear $p(x)$-Kirchhoff systems with dynamic boundary
conditions, which involve nonlinear external damping terms $Q$ and
nonlinear driving forces $f$. Through the study of the natural
energy associated to the solutions $u$ of the systems, the
nonexistence of global solutions, when the initial energy is
controlled above by a critical value was proved. And the
$p$-Kirchhoff equations involving the quasilinear homogeneous
$p$-Laplace operator were extended to the $p(x)$-Kirchhoff equations
which have been used in the last decades to model various
phenomena.

Key words: $p(x)$-Kirchhoff systems, global non-existence, nonlinear source and boundary damping terms
