Several Theorems on Single and Set-Valued Presic Type Mappings

In this study, we introduce set-valued Presic type almost contractive mapping, Presic type almost F-contractive mapping and set-valued Presic type almost F-contractive mapping in metric space and prove some fixed point results for these mappings. Additionally, we give examples to show that our main theorems are applicable. These examples show that the new class of set-valued Presic type almost F-contractive operators is not included in Presic type class of set-valued Presic type almost contractive operators.
