摘要：
In this research paper, we attempt to investigate the generalization of the well-known properties of compact operators in quaternionic Hilbert spaces resulting from the study of general operators, especially spectral features of demicompact operators in quaternionic Hilbert spaces. Further more, we introduce the ellipsoid spectrum and display some properties about this new concept.
