摘要
基于全连续算子的延拓定理连同Leray-Schauder度理论,给出了著名的Schauder不动点定理和Rothe不动点定理的新的比较简洁的证明.
Based on the continuation theorem of completely continuous operators together with Leray-Schauder degree theory,this paper gives new and concise proofs of the famous Schauder fixed point theorem and Rothe fixed point theorem.
