全校師生:
我校定于2019年11月30日舉辦研究生靈犀學(xué)術(shù)殿堂——侯耀平教授報(bào)告會(huì),現(xiàn)將有關(guān)事項(xiàng)通知如下:
1.報(bào)告會(huì)簡(jiǎn)介
報(bào)告人:侯耀平教授
時(shí)間:2019年11月30日(星期六)上午8:30—9:30
地點(diǎn):友誼校區(qū)誠(chéng)字樓429
報(bào)告題目:On the spectrum and Zeta function of a graph
內(nèi)容簡(jiǎn)介:In this talk, we present the Ihara zeta function of the cone over a semiregular bipartite graph and show that they are cospectral if and only if they have the same Ihara zeta function. We also present the decomposition formulae for the zeta functions of families of graphs obtained through corona-type construction and construct some families of graphs with the same zeta function by the spectra of these graphs. We present relations between the invariants of a graph can be obtained from the partial derivatives at some point of a determinant in terms of its Bartholdi zeta function.
2.歡迎各學(xué)院師生前來(lái)聽(tīng)報(bào)告。報(bào)告會(huì)期間請(qǐng)關(guān)閉手機(jī)或?qū)⑹謾C(jī)調(diào)至靜音模式。
