摘要:

The eccentricity $\varepsilon_G(v)$ of a vertex $v$ in a graph $G$ is the maximum distance from $v$ to other vertices in $G$. The eccentricity is a fundamental concept in metric graph theory. In this talk we report some results on the mathematical properties of several special eccentricity-based graphs, including almost self-centered (ASC) graphs and almost-peripheral (AP) graphs, and the minimum embedding of general graphs into them.
