摘　　要：1 Introduction We want to investigate the following boundary value problem:where m】1, n】1, p≥1 and m】p. As for a, the following properties will be assumed: (A.1) a(r)∈C^1 ([0, ∞)) and a(r)】0 for any r∈(0, ∞); (A.2) there exists α】0 such that (r-α)a(r)≥0 for any r∈[0, ∞). The initial value problem corresponding to (1.1) is the following Cauchy problem:
