Near-linear algebra
Abstract
In this paper, we prove that the world of near-vector spaces allows us to work with non-linear problems and yet, gives access to most of the tools linear algebra has to offer. We establish some fundamental results for near-vector spaces toward extending classical linear algebra to near-linear algebra. In the present paper, we finalize the algebraic proof that any non-empty -subspace stable under addition and scalar multiplication is an -subspace. We demonstrate that any quotient of a near-vector space by an -subspace is a near-vector space and the First Isomorphism Theorem for near-vector spaces. In doing this, we obtain fundamental descriptions of the span. Defining linear independence outside the quasi-kernel, we prove that near-vector spaces are characterized in terms of the existence of a scalar basis, and we obtain a new important notion of basis.
