报告内容简介：In this talk, I first recall some recent research on the stability of isometries in Banach spaces. Then I introduce some reuslts on strongly separating subspaces of continuous functions and their boundaries. In the end, I show a stability result on non-surjective isometries between strongly separating subspaces of continuous functions, and give an example to show this result is optimal.
