Title	Existence of an interval of principal eigenvalues for radially symmetric problems on all of RN
Type	JournalPaper
Keywords	Principal eigenvalues; Radially symmetric problems; Sturm comparison theorem
Abstract	We investigate the existence of principal eigenvalues, i.e., values of for which the corresponding eigenfunction is positive, for the radially symmetric problem − u(x) = g(x)u(x) for x ∈ RN , where g is a radially symmetric smooth bounded function which changes sign on [0,∞).
