Abstract

This paper is concerned with the existence, stability and almost periodicity of global bounded solutions of linear and semilinear parabolic equations. We give a rather complete characterization to the linear equation ut Du 1⁄4 luþ f ðx; tÞ, in term of the parameter l, of whether or not the global bounded solutions exist. Also, we obtain a complete characterization on the stability of global bounded solutions.

热方程解的整体有界性、稳定性和概周期性
研究了一类线性和半线性抛物型方程整体有界解的存在性、稳定性和概周期性。我们给出了线性方程ut Du 1 / 4 luþ f ðx的较为完整的表征;TÞ,用参数l表示,全局有界解是否存在。同时,我们也得到了全局有界解稳定性的完整表征。
