摘要
In this paper, we study the uniqueness and multiplicity of positive solutions of one-dimensional prescribed mean curvature equation {-(u'/root 1 - u'(2))' = lambda f(u), u(x) > 0, -1 < x < 1, u(-1) = u(1) = 0, where lambda is a positive parameter. The main tool is the fixed point index in cones.
