SUMMARY
Recall that an operator T in scrB (X) admits a generalized Kato decomposition, (GKD for short), if there exists (X1, X2 ) in Red(T ) such that Tshortmid X1 is semiregular and Tshortmid X2 is quasi-nilpotent, in this case T is said tobe a pseudo Fredholm operator. Clearly, every semi-regular operator is of Kato type and a quasi-nilpotent operator has a GKD, for more information about generalized . . .
