In the video, it is explained how the Yoneda Lemma can be used to understand complex structures. The lemma states that a graph can be described in two ways: as a single vertex graph and as a graph composed of directed edges between the vertices. The yoni dilemma states that this duality between these descriptions is a way to communicate that a vertex is the source of an edge.
In this video, the Yoneda Lemma is explained in detail. This theorem states that if there is a natural transformation from a single vertex graph to a graph with multiple edges, then the vertex represented by this transformation is the source of that edge. This is a powerful tool for understanding complex relationships between objects.
The Yoneda Lemma is a fundamental result in category theory which states that any two vertices in a graph can be described in terms of their sources and targets. This video introduces the concept and shows how it can be used to understand the structure of objects.
