Semi - Fredholm Operator and its Perturbations |
| |
| Abstract: | This paper discusses the problems in ralation to linear semi-Fredholm operator. Such sufficient conditions are obtained that the sum T+A of a semi --- Fredholm operator T and other perturbation operator A also becomes a semi - Fredholm operator. Perturbation theorems in Kato 1 ] are extended. |
