A data scientist is building a model to represent relationships in a knowledge graph. One key relationship is 'is_a_component_of', for example, 'a wheel is_a_component_of a car'. This relationship is asymmetric, meaning the reverse is not true ('a car is_a_component_of a wheel'). The model needs to capture this asymmetry effectively. Given that entities and relations are represented as vectors, which type of vector space provides a more inherent and powerful mechanism for modeling such asymmetric relationships?

A knowledge graph model represents entities as points and relations as transformations within a multi-dimensional space where each dimension is a complex number (a number with a real and an imaginary part). This allows relations to be modeled as element-wise rotations. Match each relational pattern with the mathematical property that the relation's representation must exhibit to effectively model that pattern.
