This concept introduces a novel way to understand "dimension" through relationships between elements rather than classical coordinate systems, topology, or vector spaces.
In traditional mathematics, dimension typically refers to the number of degrees of freedom in a space—such as 2D or 3D Euclidean space—or the number of basis vectors in a vector space. This approach is largely geometric or algebraic.
However, in complex systems—biological networks, abstract games, social graphs, ontological structures—we often encounter entities where classic notions of "space" and "dimension" do not apply, but structure does. We propose an alternate foundation: relational dimension.
