TY - JOUR T1 - On the Solvability of the Same Nonlinear Compound Boundary Valued Problems AU - Li Zhengwu, Zhang Lilong & Feng Chunhua JO - Journal of Partial Differential Equations VL - 3 SP - 248 EP - 256 PY - 1994 DA - 1994/07 SN - 7 DO - http://doi.org/ UR - https://global-sci.org/intro/article_detail/jpde/5685.html KW - Analytic function KW - nonlinear boundary valued problem KW - nonlinear singular integral equation AB - In this paper, we may make tbe following: {|W(t)| = Φ(t), \qquad t ∈ L ⊂ ∂D Re[a(t) - i ยท b(t)]W(t) = ψ(t), t ∈ M = ∂D - L equal to searching for a positive solution of nonlinear singular integral equation. The solvability and discrete approximate solution of the singular integral equation have been studied.
