摘要
We study positive solutions of the equation -Delta(g)u + lambda u = lambda u(q), with lambda > 0, q > 1 on the round sphere S-n. We reduce the equation to an ordinary differential equation by considering isoparametric functions and apply bifurcation theory. We study when the corresponding bifurcation points are transcritical. We apply this result to show the existence of degenerate solutions to the equation and to study multiplicity results for conformal constant scalar curvature metrics.
