Graph connectivity and universal rigidity of bar frameworks

A. Y. Alfakih

Let $G$ be a graph on $n$ nodes. In this note, we prove that if $G$ is $(r + 1)$ -vertex connected, $1 \leq r \leq n - 2$ , then there exists a configuration $p$ in general position in $…

On Farkas Lemma and Dimensional Rigidity of Bar Frameworks

A. Y. Alfakih

We present a new semidefinite Farkas lemma involving a side constraint on the rank. This lemma is then used to present a new proof of a recent characterization, by Connelly and Gor…
