摘要 | This paper is concerned with the existence and uniqueness of positive solutions for the fourth order Kirchhoff type problem {u ''''(x) - (a+b integral(1)(0)(u'(x))(2)dx)u ''(x) =lambda f(u(x)), x is an element of (0,1), i(0) = u(1) = u ''(0) u ''(1) = 0, where a > 0, b >= 0 are constants, lambda is an element of R is a parameter. For the case f (u) = u, we use an argument based on the linear eigenvalue problems of fourth order equations and their properties to show that there exists a unique positive solution for all lambda > lambda(1,a), here lambda(1,a) is the first eigenvalue of the above problem with b = 0; for the case f is sublinear, we prove that there exists a unique positive solution for all lambda > 0 and no positive solution for l < 0 by using bifurcation method. |
