The sandwich theorem

open access: yesThe Electronic Journal of Combinatorics, 1993
This report contains expository notes about a function $\vartheta(G)$ that is popularly known as the Lov\'asz number of a graph~$G$. There are many ways to define $\vartheta(G)$, and the surprising variety of different characterizations indicates in ...
