In this manuscript we introduce the notion of \((\alpha,\beta,\psi,\phi)\)-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.

在这份手稿中,我们引入了\((\alpha,\beta,\psi,\phi)\) -插值收缩的概念,它统一和概括了重要的概念:Proinov 型收缩、插值收缩和充足的频谱收缩。我们研究了保证此类映射不动点的存在性和唯一性的充分必要条件。
