take rule allows a subject to take rights of another object (add an edge originating at the subject) grant rule allows a subject to grant own rights to another object (add an edge terminating at the subject) create rule allows a subject to create new objects (add a vertex and an edge from the subject to the new vertex) remove rule allows a ...

In graph theory, the graph removal lemma states that when a graph contains few copies of a given subgraph, then all of the copies can be eliminated by removing a small number of edges. [1] The special case in which the subgraph is a triangle is known as the triangle removal lemma .

Graph theory is the branch of mathematics that examines the properties of mathematical graphs. See glossary of graph theory for common terms and their definition. Informally, this type of graph is a set of objects called vertices (or nodes) connected by links called edges (or arcs), which can also have associated directions.
The reverse-delete algorithm is an algorithm in graph theory used to obtain a minimum spanning tree from a given connected, edge-weighted graph. It first appeared in Kruskal (1956) , but it should not be confused with Kruskal's algorithm which appears in the same paper.
Edge contraction is used in the recursive formula for the number of spanning trees of an arbitrary connected graph, [7] and in the recurrence formula for the chromatic polynomial of a simple graph. [8] Contractions are also useful in structures where we wish to simplify a graph by identifying vertices that represent essentially equivalent entities.
The choosability (or list colorability or list chromatic number) ch(G) of a graph G is the least number k such that G is k-choosable. More generally, for a function f assigning a positive integer f(v) to each vertex v, a graph G is f-choosable (or f-list-colorable) if it has a list coloring no matter how one assigns a list of f(v) colors to ...
