AI 中文摘要
通过光滑线性算子的作用和一族给定Banach空间中有限多个非线性项,利用常数变易公式求解半线性发展方程。确定了初始条件的容许空间,以保证适当意义下解的存在唯一性。分析了其最大存在时间、短时和爆破时间轮廓、全局可延拓性及正则性。对于Banach空间的外推分数幂尺度,证明了相应Cauchy问题的可解性。给出了在R^N中修正粘性Cahn-Hilliard方程、不同基因型细胞群体演化以及半线性Schrödinger方程中的应用实例。
英文摘要
Semilinear evolution equations are solved by means of the variation of constants formula under the action of smoothing linear operators and a finite number of nonlinearities operating between chosen Banach spaces of a given family. Admissible spaces of initial conditions are determined for the existence and uniqueness of a suitable notion of solution. Its maximal time of existence, short time and blow up time profiles, global extendibility and regularity are analyzed. For extrapolated fractional power scale of Banach spaces the fulfillment of the corresponding Cauchy problem is shown. Chosen applications to the modified viscous Cahn-Hilliard equation in R^N, the evolution of cell population of varying genotype and the semilinear Schrödinger equation are presented.
