燃烧理论中一类系统径向平稳解的存在性

Existence of radial stationary solutions for a system in combustion theory

Jerome Coville, Juan Davila

摘要:

本文从具有辐射损失的火焰球模型出发,构造了一类非线性非合作椭圆方程组的径向对称解。该模型是基于一个一步动力学反应和我们的系统是通过近似的标准Arrhenius定律的点火非线性,并通过简化的长期模型辐射。我们利用度理论证明了2个解的存在性。

英文摘要:

In this paper, we construct radially symmetric solutions of a nonlinear noncooperative elliptic system derived from a model for flame balls with radiation losses. This model is based on a one step kinetic reaction and our system is obtained by approximating the standard Arrehnius law by an ignition nonlinearity, and by simplifying the term that models radiation. We prove the existence of 2 solutions using degree theory.
