Positive solutions for the beam equation under certain boundary conditions. <i>Electronic Journal of Differential Equations, 2005</i>(78), pp. 1-8.1072-6691https://hdl.handle.net/10877/13679We consider a boundary-value problem for the beam equation, in which the boundary conditions mean that the beam is embedded at one end and fastened with a sliding clamp at the other end. Some priori estimates to the positive solutions for the boundary-value problem are obtained. Sufficient conditions for the existence and nonexistence of positive solutions for the boundary-value problem are established.Text8 pages1 file (.pdf)enAttribution 4.0 InternationalFixed point theoremConeNonlinear boundary-value problemsPositive solutionsArticle
