Principal Values and Principal Subspaces of Two Subspaces of Vector Spaces with Inner Product

Ice B. Risteski, Kostadin G. Trenčevski

In this paper is studied the problem concerning the angle between two subspaces of arbitrary dimensions in Euclidean space $E_{n}$ . It is proven that the angle between two subspace…

A formula for the k-th covariant derivative

Kostadin Trenčevski

The aim of the present paper is to give a formula for the $k$ -th covariant derivative of tensor field along a given curve. In order to do that, first the symbols $P_{j}^{i < k >}$ and…

On a generalized n-inner product and the corresponding Cauchy-Schwarz inequality

Kostadin Trenčevski, Risto Malčeski

In this paper is defined an $n$ -inner product of type $⟨ a_{1}, \dots, a_{n} ∣ b_{1} \dots b_{n} ⟩$ where $a_{1}, \dots, a_{n}$ , ${\bf b}_1,…
