Global structure of radial positive solutions for a prescribed mean curvature problem in a ball

In this paper, we are concerned with the global structure of radial positive solutions of boundary value problemdiv(ϕN(∇v))+λf(|x|,v)=0inB(R),v=0on∂B(R), where ϕN(y)=y1−|y|2, y∈RN, λ is a positive parameter, B(R)={x∈RN:|x|
