摘要: 研究一类发展型p-Laplace方程组Cauchy问题弱解 的存在惟一性. 利用抛物正则化方法建立了弱解的存在性, 并通过把相应的Cauchy问题转化为一个方程的情形, 再结合能量估计和衰减估计两种方法, 得到了弱解的惟一性.

Abstract: The existence and uniqueness of weak solutions for the Cauchy problem of an evolutionary Laplacian systems were investigated. The exsitence was obtained by virtue of the parabolic regularized method. Owing to the difficulty of the comparison between the two solutions of the system consided, wecombined the enery method with the decay method to reduce our problem to the scalar case, so as to establish the uniqueness of solution.

Key words: nonlinear diffusion system, existence, uniqueness, absorption, p-Laplacian system
