The semilinear elliptic eigenvalue problem with superlinear pure power nonlinearity is considered. This problem is treated from the standpoint of L 2 ‐theory and the precise asymptotic formula for the eigenvalue parameter λ = λ(α) as α → ∞ is established, where α is the L 2 ‐norm of the solution u associated with λ. 2000 Mathematics Subject Classification 35P30 (primary), 35J60 (secondary).
