Keywords:η- approximation, η-co- approximation, η- orthogonal, bounded function, bounded space
The aim goal in this article, some relationships have been established of the concepts - approximation, -co- approximation and - orthogonal with the images under isometry mappings, whereas these results are generalization and expansion of - approximation, -co- approximation and - orthogonal.
