设f是2个Banach空间E和F之间C^1映射.已经证明,的广义正则点概念是f的正则点概念的一个推广并且在非线性分析和大范围分析中有非常重要的应用.用f产生的在X0∈E处的3个整数(或无穷大)值指标M(x0),Mc(x0)和Mr(x0)和分析Banach空间上有界线性算子的广义逆来刻画,的广义正则点,即,如果f'(x0)在从E上到F的有界线性算子组成的Banach空间B(E,F)内有广义逆,且M(x0),Mc(x0)和Mr(x0)中至少有一个是有限,则x0是f的广义正则点的充分必要条件是多重指标(M(x),Mc(x),Mr(x))在x0点处连续.
Let f be a C^1 map between two Banach spaces E and F. It has been proved that the concept of generalized regular points of f, which is a generalization of the notion of regular points of f, has some crucial applications in nonlinearity and global analysis. We characterize the generalized regular points of f using the three integer-valued (or infinite) indices M(x0), Mc(x0) and Mr(x0) at x0 ∈ E generated by f and by analyzing generalized inverses of bounded linear operators on Banach spaces, that is, iff '(x0) has a generalized inverse in the Banach space B(E, F) of all bounded linear operators on E into F and at least one of the indices M(x0), Mc(x0) and Mr(x0) is finite, then xo is a generalized regular point off if and only if the multi-index (M(x), Me(x), Mr(x)) is continuous at X0.
