Existence and Uniqueness of Solutions to Singular Impulsive Delay Boundary Value Problems via Paired-Chatterjea-Type Contractions

We establish the existence and uniqueness of solutions to a class of second-order nonlinear boundary value problems involving impulses, delay, and possible singularities. The approach leverages the recent notion of paired-Chatterjea-type contractions. Under a smallness condition ensuring the associa...
