Abstract

This work is concerned with the following first-order dynamic equation on time scale 𝕋 , 𝑥 Δ ( 𝑡 ) + 𝑝 ( 𝑡 ) 𝑥 ( 𝜎 ( 𝑡 ) ) = 𝑓 ( 𝑡 , 𝑥 ( 𝑡 ) ) , 𝑡 [ 0 , 𝑇 ] 𝕋 with the nonlinear boundary condition 𝑥 ( 0 ) = 𝑔 ( 𝑥 ( 𝜎 ( 𝑇 ) ) ) . By applying monotone iteration method, we not only obtain the existence of positive solutions, but also establish iterative schemes for approximating the solutions.
