On ψ-projective expansion, quasi partial metrics aggregation with an application
Pooja Dhawan,Jatinderdeep Kaur,Vishal Gupta
Keywords:Fixed point; quasi partial metric space; aggregation function; projective expansion.
      In the present article, the notion of expansion between quasi partial metric spaces through aggregation is defined. With the help of aggregation functions, the concept of projective Psi-expansion has been introduced and some fixed point results are obtained through this notion. Furthermore, sufficient conditions are provided to characterize aggregation function to ensure the existence and uniqueness of fixed point. Also, an application to asymptotic complexity analysis is presented after the results.
