✍ Sandi Klavžar 📂 Article 📅 1994 🏛 Elsevier Science 🌐 English ⚖ 663 KB

It is proved that a split graph is an absolute retract of split graphs if and only if a partition of its vertex set into a stable set and a complete set is unique or it is a complete split graph. Three equivalent conditions for a split graph to be an absolute retract of the class of all graphs are g

A graph H is an absolute retract if for every isometric embedding h of , , into a graph G an edge-preserving map g from G to H exists such that An absolute retract is uniquely determined by its set of embeddable vertices. We may regard this set as a metric space. We also prove that a graph (finite

The space of fuzzy sets on a compact metric space, with the sendograph metric for fuzzy sets, is shown to have the fixed point property. The relationship between absolute retracts and spaces of fuzzy sets is demonstrated. @

## Abstract The head retraction reflex (HRR) is a vestigial withdrawal reflex of the face and is suppressed in healthy subjects. We investigated the prevalence and electrophysiological patterns of the HRR in patients suffering from stiff‐man syndrome (SMS, n = 28) and related disorders, stiff‐limb
