$H$-projecting in $n$-dimensional Euclidean space $E^n$

Abstract

Several types of projecting in $n$-dimensional Euclidean spaces are known. In this article we define a new type of projecting of the $n$-dimensional Euclidean space onto its fixed plane. We shall prove some properties of this projecting. It will be shown that so defined projecting is a central projectingwith an $(n-3)$-dimensional subspace as a center.
