Ma J P给出了Banach空间中Fredholm映射的秩定理,运用广义逆理论和局部精细点来对上述结果进行推广,给出了C^k-Banach流形之间Fredholm映射的秩定理.
Ma J P given the rank theorem for Fredholm map between Banach spaces. Using of the generalized inverse theory and the definition of local fine point to extend this theorem, given the rank theorem for Fredholm map between C^k-Banach manifolds.
