Some properties of bounded tri-linear maps
Abotaleb Sheikhali, Ali Ebadian, Kazem Haghnejad Azar
Let and be normed spaces and be a bounded tri-linear mapping. In this Article, we define the topological centers for bounded tri…
Regularity of bounded tri-linear maps and the fourth adjiont of a tri-derivation
Abotaleb Sheikhali, Ali Ebadian, Kazem Haghnejad Azar
In this Article, we give a simple criterion for the regularity of a tri-linear mapping. We provide if is a bounded tri-linear mapping and $h…
Close-to-regularity and completely regularity of bounded tri-linear maps
Abotaleb Sheikhali, Ali Ebadian, Kazem Haghnejad Azar
Let be a bounded tri-linear map on normed spaces. We say that is close-to-regular when and we say that is co…
Finite sum of weighted composition operators with closed range
Saeedeh Shamsigamchi, Abolghasem Alishahi, Ali Ebadian
In this paper, first we characterize closedness of range of the finite sum of weighted composition operators between different Lp-spaces. Then we discuss polar decomposition and in…
