一类拟线性椭圆型方程组的Keller-Osserman估计

Keller-Osserman estimates for some quasilinear elliptic systems

Marie-Françoise Bidaut-Véron, Marta Garcia-Huidobro, Cecilia Yarur

摘要:

本文研究R^{N}中区域$Ω$中两类方程的拟线性多幂方程组:具有吸收项或混合项。尽管缺乏比较原理,我们证明了先验估计的Keller-Osserman型。对于混合制系统,我们证明了其中一个解总是满足Harnack不等式.在$Ω$ =B(0,1)\{0}的情形下,我们还研究了更一般的加权系统的解在0附近的行为,给出了先验估计和可移性结果.最后证明了结果的清晰性。

英文摘要:

In this article we study quasilinear multipower systems of two equations of two types, in a domain $Ω$ of R^{N} : with absorption terms, or mixed terms. Despite of the lack of comparison principle, we prove a priori estimates of Keller-Osserman type. Concerning the mixed system, we show that one of the solutions always satisfies Harnack inequality. In the case $Ω$=B(0,1)\{0}, we also study the behaviour near 0 of the solutions of more general weighted systems, giving a priori estimates and removability results. Finally we prove the sharpness of the results.
