**Minisymposium:**
CHEMICAL GRAPH THEORY

**Content:**
In this talk we will give a unified viewpoint on indices, polynomials and matrices of graphs. Starting from a graph with weights on edges or vertices, one can get various kinds of graph indices, graph polynomials, and graph matrices. Then, we can see that a lot of new and interesting objects can be taken into account for further studies.
