We deal with the generalized Emden–Fowler equation f ″ ( x ) + g ( x ) f − θ ( x ) = 0, where θ ∈ R , x ∈ ( a , b ) , g belongs to L p (( a , b )). We obtain a priori estimates for the solutions, as well as information about their asymptotic behavior near boundary points. As a tool, we derive new nonlinear variants of first‐order and second‐order Poincaré inequalities, which are based on strongly nonlinear multiplicative inequalities obtained recently by first author and Peszek.
