We first attempt to determine conditions on a linear relation T such that μT becomes a demicompact linear relation for each μ ∈ [0,1)(see Theorems 2.4 and 2.5). Second, we display some results on Fredholm and upper semi-Fredholm linear relations

We unfold in this paper two main results. In the first, we give the necessary assumptions for three linear relations $A$, $B$ and $S$ such that $\sigma_{eap,S}(A+B)= \sigma _{eap,S}(A)$ and $\sigma_{e\delta,S}(A+B)= \sigma_{e\delta,S}(A)$ is true. In

In this research paper, we address the local spectral properties of an upper triangular linear relations matrix $$M_{C}$$ defined by $$M_{C}=\left( \begin{array}{cc} A &{} C \\ 0 &{} B \\ \end{array} \right) ,$$ on $$X\oplus Y$$ where $$A \in \mathca

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
