  2. Chemical graph theory - Wikipedia

    en.wikipedia.org/wiki/Chemical_graph_theory

    Chemical graph theory is the topology branch of mathematical chemistry which applies graph theory to mathematical modelling of chemical phenomena. [1] The pioneers of chemical graph theory are Alexandru Balaban, Ante Graovac, Iván Gutman, Haruo Hosoya, Milan Randić and Nenad Trinajstić [2] (also Harry Wiener and others). In 1988, it was ...

  3. Mathematical chemistry - Wikipedia

    en.wikipedia.org/wiki/Mathematical_chemistry

    Mathematical chemistry [1] is the area of research engaged in novel applications of mathematics to chemistry; it concerns itself principally with the mathematical modeling of chemical phenomena. [2] Mathematical chemistry has also sometimes been called computer chemistry , but should not be confused with computational chemistry .

  4. Alexandru Balaban - Wikipedia

    en.wikipedia.org/wiki/Alexandru_Balaban

    He is considered as one of pioneers of chemical graph theory. The first book about this interdisciplinary field was edited by Balaban and appeared in 1976: Chemical Applications of Graph Theory. One area in which cubic (or trivalent) graphs play a dominant role is the enumeration of [n]annulene valence isomers (CH) n where n is an even

  5. Molecular graph - Wikipedia

    en.wikipedia.org/wiki/Molecular_graph

    In chemical graph theory and in mathematical chemistry, a molecular graph or chemical graph is a representation of the structural formula of a chemical compound in terms of graph theory. A chemical graph is a labeled graph whose vertices correspond to the atoms of the compound and edges correspond to chemical bonds.

  6. Nenad Trinajstić - Wikipedia

    en.wikipedia.org/wiki/Nenad_Trinajstić

    His scientific interests are quantum chemistry, mathematical chemistry, chemoinformatics, history of chemistry and philosophy of natural science. He wrote the first monograph on chemical graph theory [ 3 ] and introduced several molecular descriptors such as 3-dimensional Wiener index [ 4 ] and Zagreb indices (with Ivan Gutman), [ 5 ] which are ...

  7. Graph theory - Wikipedia

    en.wikipedia.org/wiki/Graph_theory

    A drawing of a graph with 6 vertices and 7 edges.. In mathematics and computer science, graph theory is the study of graphs, which are mathematical structures used to model pairwise relations between objects.

  8. Topological index - Wikipedia

    en.wikipedia.org/wiki/Topological_index

    In the fields of chemical graph theory, molecular topology, and mathematical chemistry, a topological index, also known as a connectivity index, is a type of a molecular descriptor that is calculated based on the molecular graph of a chemical compound. [1]

  9. Wiener index - Wikipedia

    en.wikipedia.org/wiki/Wiener_index

    In chemical graph theory, the Wiener index (also Wiener number) introduced by Harry Wiener, is a topological index of a molecule, defined as the sum of the lengths of the shortest paths between all pairs of vertices in the chemical graph representing the non-hydrogen atoms in the molecule.
