Moreover, we give an application to the existence of multiple solutions for a nonlocal boundary value problem that models the displacement of a beam subject to some feedback controllersengAttribution 4.0 Internationalhttp://creativecommons.org/licenses/by/4.0/Krasnosel’skii fixed point theoremPositive solutionsConical shellsMultiplicity1202 Análisis y análisis funcionaljournal article10.1186/1687-1812-2013-1252730-5422open access
