OICC Press Communications in Nonlinear Analysis 2371-7920 3 1 2025 11 09 Existence of positive solutions to a coupled system with three­point boundary conditions via degree theory EN S. Samina Kamal Shah Rahmat Ali Khan Journal Article 2025 11 09 In this paper, we study the existence of solutions of nonlinear fractional hybrid differential equations. Byusing the topological degree theory, some results on the existence of solutions are obtained. The results aredemonstrated by a proper example. Coupled system fractional derivative green function growth condition topological degree theory fixed-point theorem
