Estimates for Eigenvalues of Polyharmonic Operator △~p
Mi Wang · Journal of Hebei University · 1999
Let Ω be a bounded domain in Rm, m≥2, with sufficiently smooth boundry.The eigenvalue problem of polyharmonic operator △p with any order is studied, a lower estimate for the eigenvalue of the operator △p is provided, which depends only on the volume of Ω.
