Abstract: The article "On the discrete part of the spectrum of an elliptic operator" examines the study of the nature of the spectrum, which consists in studying a set of spectral points depending on the behavior of coefficients in a differential operation, the type and nature of boundary value problems. The question of the structure of the spectrum of differential operators is important. Special attention is paid to the construction of functional calculus and the proof of the spectral theorem in its various formulations.
Key words: operator, discreteness of the spectrum, differential operation, set, inequality.
