During the Eighth National Games held in August of last year, their daughter Wu Yanyan broke a world record, thus becoming the toast of Guangxi Zhuang Autonomous Region. Friends and relatives swarmed to their home to express their congratulations. And at the Guangxi Daily, where Wu Guanzhong works as a driver, Wu Yanyan was declared the pride of the whole staff. Wu Guanzhong still remembers a happy encounter he had with a shopowner. Taking the certificate issued by the International Amateur Swimming Federation (FINA) confirming Yanyan’s world record,展开更多

The resulting graph is called a fan-shaped graph. The corresponding zero-divisor semigroups have been completely determined by Tang et al. for n = 2, 3, 4 and by Wu et al. for n ≥ 6, respectively. In this paper, we study the case for n = 5, and give all the corresponding zero-divisor semigroups of Fn.展开更多
