中文摘要 | 本文主要利用Leray-Schauder度論來解一致方程式Lu=Fu,這�隿為一有界線性算 子,F 為一非線性算子,當然我們須轉換一致方程式成可利用 Leray-Schauder 度論的型式 ,即 u=Tu,T 為一緊緻算子, 而此抽象結果我們可用來證明某些擬線性橢圓型式邊界值問 題廣義解的存在。 |
英文摘要 | In this paper we use the Leray-Schauder degree theory to solve the coincidence equation Lu=Fu, where L:X → Y is a bouned linear operator and F: X → Y is a nonlinear operator. For convenience to use of the Leray-Schauder dagree theory we must transform the coincidence equation to an equation of fixed point type i.e., u=Tu, u �e E, T is compact for some suitable Banach space E. Our abstract results are applied to the existernce of generalized solution of quasilinear elliptic boundary value problems at resonance. |
