Terwilliger algebra of a commutative association scheme was successfully used for studying distance-regular graphs. However, this notion can be easily generalized to an arbitrary finite, simple and connected graph. In many instances, this algebra can be better studied via its irreducible modules. In this talk, we show how to relate the module structure of the Terwilliger algebra of a graph with the concept of local distance-regularity. Finally, we investigate how this algebra can be used as an effective tool for studying some combinatorial properties in the graph.

This is joint work with Stefko Miklavic.
