A class of unbounded operators, namely, class-\(\mathcal {A}\) operators, are introduced and studied by considering Weyl's theorem and its variants. Also, the present paper discusses the spectral properties of class-\(\mathcal {A}\) operators, focusing on the isolated spectral points, the Weyl spectrum, and the B-Weyl spectrum.
