Abstract
Orthogonality concept is a powerful mathematical tool that
makes possible the formulation of some mathematical conjectures
to prove some important theorems in Mathematics for the
solution of real and imaginary problems. There are different
notions of orthogonality in normed linear spaces. The concept
of orthogonality has certain properties- symmetry, homogeneity,
additivity and so on. In this work, the properties of orthogonality
as applied to normed linear spaces are investigated and the com
parisons between the different notions of orthogonality are shown.
