Popis: We study the second order singular boundary value problem u ″ + λ f ( t , u ) = 0 , t ∈ ( 0 , 1 ) , u ( 0 ) = ∫ 0 1 u ( s ) d ξ ( s ) , u ( 1 ) = ∫ 0 1 u ( s ) d η ( s ) . Sufficient conditions are obtained for the existence and uniqueness of positive solutions. The dependence of positive solutions on the parameter λ is also studied. Moreover, application of our theory to a special problem is discussed. To prove our theorem, we utilize some results from the mixed monotone operator theory.
