Haruo Hosoya is a Japanese mathematician known for his work in the field of mathematical biology, graph theory, and combinatorics. One of his significant contributions is the Hosoya index, a topological descriptor used in chemistry to characterize the structure of molecular graphs. The Hosoya index counts the number of different walks in a graph, which can relate to various properties of the molecules represented by those graphs.
