dc.description.abstract [EN] We discuss several properties of Q-functions in the sense of Al-Homidan et al.. In particular, we prove that the partial metric induced by any T0 weighted quasipseudometric space is a Q-function and show that both the Sorgenfrey line and the Kofner plane provide signi¿cant examples of quasimetric spaces for which the associated supremum metric is a Q-function. In this context we also obtain some ¿xed point results for multivalued maps by using Bianchini-Grandol¿ gauge functions. es_ES
