Let . When λ is large, we prove the existence of a smooth curve consisting of radially symmetric and radially decreasing solutions concentrating on . Moreover, checking the transversality condition, we show that this curve has infinitely many symmetry breaking bifurcation points from which continua consisting of nonradially symmetric solutions emanate. If , then the closure of each bifurcating continuum is locally homeomorphic to a disk. When the domain is a rectangle , we show that a curve consisting of one-dimensional solutions concentrating on has infinitely many symmetry breaking bifurcation points. Extending this solution with even reflection, we obtain a new entire solution.
