The $k$-core of a graph is unique and it can be obtained by iteratively deleting vertices of degree smaller than $k$. The $k$-core of a graph that already has minimum degree at least~$k$ is the graph itself. So we...

Given a formal language $L$ over an alphabet $\Sigma$, the left quotient $u^{-1}L$ of $L$ by a word $u$ is defined as the l...
