### GROUP PROPERTIES AND GROUP ISOMORPHISM

Here we are using the theorem Theorem 1: If two groups are **isomorphic**, they must have the same order. Proof: By definition, two groups are **isomorphic** if there exist a 1-1 onto mapping ϕ from one group to the other.

### Graph Theory

In practice, it is not a simple task to prove that two graphs are **isomorphic**. It is much simpler to show that two graphs are not **isomorphic** by showing an invariant property that one has and other does not.

### Introduction to Graph Theory

Isomorphism The word isomorphism cames from Greek roots, its meaning is roughly "equal shapes."We say that two graphs are **isomorphic** if there isa function û that maps the vertex set of one graph to the vertex set of the other; additionally, this function must be a bijection (one-to-one and onto) and it ...

### An Effective Approach for Solving Subgraph Isomorphism Problem

This is based on the path heuristic: Given two graphs G 1 and G 2, if G 1 is **isomorphic** to G 2 then a path in G 1 must be **isomorphic** to a path in G 2. 3.2.4 Policy Functions The planning model provides two domain-independent guiding principles as the policy functions for TEU identification and SEU selection [12].
