International Conference of Mathematical Sciences (ICMS 2019). s. 49.978-605-2124-29-1https://hdl.handle.net/20.500.12415/2112In this note we study the properties (UWE) and (WE) are the variant of Weyl’s theorem. We establish for a bounded linear operator defined on a Banach space several sufficient and necessary conditions for which property (UWE) holds. We also relate this property with property (UW?), and we show that if T is polaroid and T satisfies property (UWE) then properties (UWE) and (UW?) are equivalent under functional calculus f(T).enCC0 1.0 Universalinfo:eu-repo/semantics/openAccessProperty (UWn)B-Weyl spectrumProperty (UWE)Article4949
