摘要 通过选择恰当的检验函数与平移讨论相结合,给出了一类非线性项具有非局部性质的波动方程局部解和全局解存在的必要条件. In this paper,using a method based on a duality argument with an appropriate choice of the test function and a scaling argument,we establish some conditions that ensure the absence of global solutions to a wave equation with a nonlocal nonlinearity and obtain necessary conditions for the local and global solvability.
