本文研究了光滑有界区域Ω <$RN中的奇异抛物型方程组ut = Δ u+ f(x)v− p,vt = Δ v+ g(x)u− q,初始条件为u 0(x),v0(x)> 0,Dirichlet条件为零.这个问题很有趣,因为它与生物学和物理学中的一些问题有关。在适当的p,q和f(x),g(x)的假设下,利用泛函方法得到了弱解和经典解的存在性结果.这种方法是由文[4]和[5]中处理奇异抛物方程组的结果以及相关文献所激发的。
In this paper, we are concerned with the singular parabolic system u t= Δ u+ f (x) v− p, v t= Δ v+ g (x) u− q in a smooth bounded domain Ω⊂ R N subject to zero Dirichlet conditions, with initial conditions u 0 (x), v 0 (x)> 0. This problem is of interest as it is related to some problems in biology and physics. Under suitable assumptions on p, q and f (x), g (x), some existence results of weak and classical solutions are obtained using a functional method. This method is motivated by such results found in [4] and [5] when dealing with singular parabolic systems and the related references within.
