Topological index — For topological index in mathematics, see Atiyah–Singer index theorem. 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… … Wikipedia
Isomer — This article is about the chemical concept. For isomerism of atomic nuclei, see nuclear isomer. In chemistry, isomers (from Greek ἰσομερής, isomerès; isos = equal , méros = part ) are compounds with the same molecular formula but different… … Wikipedia
Topoisomer — Topoisomers or topological isomers are molecules with the same chemical formula and stereochemical bond connectivities but different topologies. Examples of molecules for which there exist topoisomers include DNA, which can form knots, and… … Wikipedia

Topoisomerase — Topoisomerases (type I: EC 5.99.1.2, type II: EC 5.99.1.3) are enzymes that regulate the overwinding or underwinding of DNA. The winding problem of DNA arises due to the intertwined nature of its double helical structure. For example, during DNA… … Wikipedia
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… … Wikipedia
Hosoya index — The Hosoya index, also known as the topological index or Z index of a graph is the total number of matchings in it plus 1 ( plus 1 accounts for the number of matchings with 0 edges). Its computational complexity is O(exp(E)), where E is number of … Wikipedia
