Remarks on a non-local boundary value problem. (English) Zbl 1186.34029

Summary: We remark that results on existence of symmetric positive solutions obtained in some recent papers can, in fact, be deduced as special cases of some known results. We also correct the values of the principal eigenvalue previously given in some examples.
