ON GAPS BETWEEN BOUNDED OPERATORSDragana Cvetkovi\'cPrirodnomatemati\v cki fakultet, Ni\v s, YugoslaviaAbstract: 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. 212213, 501503 (1994; Zbl 0812.05066)]. Keywords: Banach space; spherical gap; graphs of operators; gap between operators Classification (MSC2000): 46B20; 15A60 Full text of the article:
