Popis: Abstract In this manuscript we introduce the notion of ( α , β , ψ , ϕ ) $(\alpha,\beta,\psi,\phi)$ -interpolative contraction that unifies and generalizes significant concepts: Proinov type contractions, interpolative contractions, and ample spectrum contraction. We investigate the necessary and sufficient conditions to guarantee existence and uniqueness of the fixed point of such mappings.
