Abstract: | In this paper, we define a new operator which improves and generalizes a -Laplacian operator for some . By using this operator, we consider the existence of triple positive solutions of -point boundary value problems for some dynamic equations on time scales where is an increasing homeomorphism and positive homomorphism and . We show the existence of at least three positive solutions with suitable growth conditions imposed on the nonlinear term by using a new fixed-point theorem. |
