A tree T = (V,E) is a spanning tree for a graph G = (V0,E0) if V = V0 and E ⊆ E0. The following ﬁgure shows a spanning tree T inside of a graph G. = T Spanning trees are interesting because they connect all the nodes of a graph using the smallest possible number of edges.

WebJun 3, 2024 · Draw your K 5 knot on the torus with zero crossings. Cut your torus down a circle, twist the "torus" (now a cylinder) to a tubular trefoil, then re-glue along the original identification. This adds no additional crossings to your graph embedding, but now you are embedded into the desired space. Share Cite Follow answered Jun 3, 2024 at 4:24 Jacob In mathematics, graph theory is the study of graphs, which are mathematical structures used to model pairwise relations between objects. A graph in this context is made up of vertices (also called nodes or points) which are connected by edges (also called links or lines). A distinction is made between undirected graphs, where edges link two vertices symmetrically, and directed graphs, wh…
