In this chapter, we give out the definitionsof Cartesian product, composition, union and join for two L-graphs, which aregeneralization of the corresponding operations in graph, and the necessary conditionsthat a partial L-subgraph of these operations can be obtained by the same operationfor some partial L-subgraph of the given two L-graphs are investigated.
