Aicha Chaban, Mohammed Hichem Mortad Colloquium Mathematicum 133 (2013), 237-244 MSC: Primary 47A10, 47A60. DOI: 10.4064/cm133-2-10

Streszczenie

The present paper is mainly concerned with equations involving exponentials of bounded normal operators. Conditions implying commutativity of normal operators are given, without using the known $2\pi i$-congruence-free hypothesis. This is a continuation of a recent work by the second author.
