“…Our theorem, under the new assumptions, ensures the existence of an open interval Λ ⊆ [0, +∞) and a positive real number ρ such that, for each λ ∈ Λ, problem (P) admits at least three weak solutions whose norms in X are less than ρ. Now, for every x 0 ∈ Ω and selected r 1 , r 2 with r 2 > r 1 > 0, such that B(x 0 , r 1 ) ⊂ B(x 0 , r 2 ) ⊆ Ω, where B(x 0 , r 1 ) denotes the ball with the center at x 0 and radius of r 1 . Put…”
