An indefinite concave-convex equation under a Neumann boundary condition. II. (English) Zbl 1376.35033
The authors study some bifurcation properties for a concave-convex elliptic problem with Neumann boundary condition. A closely related paper that should be taken into account is the following: [D. Motreanu et al., Tohoku Math. J. (2) 66, No. 1, 137–153 (2014; Zbl 1296.35077)].
