Abstract

We study the existence and multiplicity of solutions for the three-point nonlinear boundary value problem https://static-content.springer.com/image/art%3A10.1155%2FJIA%2F2006%2F79653/MediaObjects/13660_2004_Article_1641_IEq1_HTML.gif , https://static-content.springer.com/image/art%3A10.1155%2FJIA%2F2006%2F79653/MediaObjects/13660_2004_Article_1641_IEq2_HTML.gif ; https://static-content.springer.com/image/art%3A10.1155%2FJIA%2F2006%2F79653/MediaObjects/13660_2004_Article_1641_IEq3_HTML.gif , where https://static-content.springer.com/image/art%3A10.1155%2FJIA%2F2006%2F79653/MediaObjects/13660_2004_Article_1641_IEq4_HTML.gif , https://static-content.springer.com/image/art%3A10.1155%2FJIA%2F2006%2F79653/MediaObjects/13660_2004_Article_1641_IEq5_HTML.gif , https://static-content.springer.com/image/art%3A10.1155%2FJIA%2F2006%2F79653/MediaObjects/13660_2004_Article_1641_IEq6_HTML.gif and https://static-content.springer.com/image/art%3A10.1155%2FJIA%2F2006%2F79653/MediaObjects/13660_2004_Article_1641_IEq7_HTML.gif are assumed to be positive and have some singularities, and https://static-content.springer.com/image/art%3A10.1155%2FJIA%2F2006%2F79653/MediaObjects/13660_2004_Article_1641_IEq8_HTML.gif is a positive parameter. Under certain conditions, we prove that there exists https://static-content.springer.com/image/art%3A10.1155%2FJIA%2F2006%2F79653/MediaObjects/13660_2004_Article_1641_IEq9_HTML.gif such that the three-point nonlinear boundary value problem has at least two positive solutions for https://static-content.springer.com/image/art%3A10.1155%2FJIA%2F2006%2F79653/MediaObjects/13660_2004_Article_1641_IEq10_HTML.gif , at least one solution for https://static-content.springer.com/image/art%3A10.1155%2FJIA%2F2006%2F79653/MediaObjects/13660_2004_Article_1641_IEq11_HTML.gif , and no solution for https://static-content.springer.com/image/art%3A10.1155%2FJIA%2F2006%2F79653/MediaObjects/13660_2004_Article_1641_IEq12_HTML.gif .
