*M*in a graph

*G*is uniquely restricted if there is no matching ${M}^{\prime}$ in

*G*that is distinct from

*M*but covers the same vertices as

*M*. Solving a problem posed by Golumbic, Hirst, and Lewenstein, we characterize the graphs in which some maximum matching is uniquely restricted. Solving a problem posed by Levit and Mandrescu, we characterize the graphs in which every maximum matching is uniquely...

*G*of order

*n*at least three, Matheson and Tarjan showed that

*G*has domination number at most $n/3$. Similarly, for a maximal outerplanar graph

*G*of order

*n*at least five, Dorfling, Hattingh, and Jonck showed, by a completely different approach, that

*G*has total domination number at most $2n/5$ unless

*G*is isomorphic to one of two exceptional graphs of order 12. We present...

*d*of nonnegative integers, let $G\left(d\right)$ and $F\left(d\right)$ be the sets of all graphs and forests with degree sequence

*d*, respectively. Let ${\gamma}_{min}\left(d\right)=min\{\gamma \left(G\right):G\in G\left(d\right)\}$, ${\alpha}_{max}\left(d\right)=max\{\alpha \left(G\right):G\in G\left(d\right)\}$, ${\gamma}_{min}^{F}\left(d\right)=min\{\gamma \left(F\right):F\in F\left(d\right)\}$, and ${\alpha}_{max}^{F}\left(d\right)=max\{\alpha \left(F\right):F\in F\left(d\right)\}$ where $\gamma \left(G\right)$ is the domination number and $\alpha \left(G\right)$ is the independence number of a graph

*G*. Adapting results of Havel and Hakimi, Rao showed in 1979 that ${\alpha}_{max}$...
