Abstract: We consider the distance between an arbitrary bounded operator on a Banach space $X$ and the null operator. The distance is computed in terms of various gaps. Thus, we generalize the J. Faghih Habibi's result from [Linear Algebra Appl. 212-213, 501-503 (1994; Zbl 0812.05066)].

Keywords: Banach space; spherical gap; graphs of operators; gap between operators

Classification (MSC2000): 46B20; 15A60
