摘要:

该文利用Crandall-Liggett半群定理和完全增长算子的性质, 得到初始值属于L1(Ω)  的非齐次发展方程第一边值问题弱解的存在性.

关键词: 完全增长算子, 半群解, 强解, 弱解

Abstract:

This paper concludes that the minimizing total variation flow with Dirichlet boundary conditions has a weak solution with initial data in L1(Ω) by using Crandall-Liggett's semigroup generation theorem and the quality of the completely accretive  operator.

Key words: Completely accretive operator, Mild solution, Strong solution, Weak solution
