摘要:

D为单位圆, T为单位圆周.设f是满足边界条件: (Δf)|T=ψf|T=f的非齐次双调和方程Δ(Δf)=g的解, 其中gC(¯D), 而ψf皆为T上的连续函数.该文建立了该族解f的边界Schwarz引理, 这一结果丰富了边界Schwarz引理在平面上的相关结果.

Abstract:

Let D be the unit disk, T the unit circle. Assume that f is a solution to inhomogeneous biharmonic equation: Δf=g, satisfying the boundary conditions: (Δf)T=ψ and f|T=f, where gC(¯D), and ψ,fC(T) are continuous functions. In this paper, we establish the boundary Schwarz lemma for solutions f, this result enriches the related results of boundary Schwarz lemma on the plane.
