This work is devoted to obtain the L p and the L ∞ -estimates of solutions via their Morse indices to the following m-Laplacian problemswhere Ω ⊂ R N is a bounded domain with smooth boundary, N > m > 2 and f ∈ C(Ω × R) which will be specified later. As far as we know, it seems to be the first time that such explicit estimates are obtained for a nonlinear degenerate problems. So, our main results extend and complement previously L ∞ -estimates results in the literature.
