報(bào)告題目：Matching anti-forcing polynomials of catacondensed hexagonal systems

報(bào)告摘要：Lei, Yeh and Zhang put forward the anti-forcing number for a perfect matching, which is the minimal cardinality over all edge subsets excluding edges in the perfect matching, but including some edges in every other perfect matching of a graph. The maximum anti-forcing number of a hexagonal system is equal to the Fries number. A counting polynomial for classifying perfect matchings possessing the same anti-forcing number was introduced by Hwang et al., using the name ‘a(chǎn)nti-forcing polynomial’. This research deduces recurrence formula of anti-forcing polynomial for catacondensed hexagonal systems. As a consequence, the continuity of the anti-forcing spectrum can be derived.

歡迎廣大師生參加！
