We study the existence of solutions for the nonlinear elliptic problem - Δ v - λ g 1 v + h 1 (v) = f 1 in V ∖ V 0 , v = 0 on V 0 , where V is the Sierpiński gasket in ℝ N - 1 ( N ≥ 2 ), V 0 is its boundary (consisting of its N corners) and λ ∈ ℝ . Here f 1 , g 1 : V → ℝ , h 1 : ℝ → ℝ are the maps satisfying suitable hypotheses.
