First we introduce the multivalued F-d-contraction on quasi metric space (X, d) and give a fixed point result related to this concept. Then taking into account the Q-function on a quasi metric space, we establish a Q-function version of this concept as multivalued F-q-contraction and hence we present a fixed point result to see the effect of Q-function to existence of fixed point of multivalued mappings on quasi metric space.eninfo:eu-repo/semantics/closedAccessQuasi metric spaceleft K-Cauchy sequenceleft K-completenessfixed pointmultivalued mappingQ-functionArticle35141502-s2.0-85063614241Q1WOS:000460760300005Q1
