Dear Mr Sutton,

Thanks for your comment. I have two questions.
1) Is the union (graph_1, graph_2) is supposed to equal union
(graph_2, graph_1) ?.

2) I want to ask if the Covariance theory [1] is applicable to solve the
problem of graph properties.
In the below example, I want to explain how I will apply the theory:
G1 is a graph representing the connection between students. So G1's
vertex_property is *student*.
G2 is a graph representing the connection between professors. So G2's
vertex_property is *professor*.
Since both *student* and *professor* are inside *people*, I can use
*people* as Union_Graph 's vertex_property.

Please let me know your opinion,
Thank you,
Tri Nguyen.
