研究了一类非线性时滞抛物方程在两类齐次边界条件下解的振动性质,获得了判别其所有解振动的充要条件,并通过实例对主要结果进行阐明.
In this paper the oscillation property of a class of nonlinear parabolic equations with several delays is discussed. A necessary and sufficient condition for oscillation of their solutions is obtained. The main results are ex plained by some examples.
