Extreme hollow hexagons with respect to the Mostar indexCruz, Roberto (Avtor) Santamaría-Galvis, Andrés (Avtor) Mostar indexhollow hexagonscut methodextremal valuesThe Mostar index of a connected graph is a well-known distance-based topologicalindex. Hollow hexagons are coronoid systems that represent coronoid hydrocarbons be-longing to the class of cycloarenes. They are formed by a single chain in a macro-cyclicarrangement consisting of linearly and angularly annelated hexagons, with exactly six an-gular hexagons. In this paper, we compute the Mostar index of hollow hexagons and findmaximal and minimal values of the Mostar index over the set of hollow hexagons with afixed number of hexagons.20252025-09-26 11:51:25Članek v reviji21797sl
