11月4日上午,應(yīng)數(shù)學(xué)與信息科學(xué)學(xué)院邀請,,美國威奇托州立大學(xué)李小龍教授為學(xué)院師生做題為“New sphere theorems under curvature operator of the second kind”的學(xué)術(shù)講座,,學(xué)院相關(guān)學(xué)科教師及研究生30余人在線共同聆聽了本次講座。
李小龍教授首先介紹了第二類曲率算子在Nishikawa-猜想被解決之后受到了極大關(guān)注,,并給出了具有第二類3-非負(fù)曲率算子的閉黎曼流形的分類,。同時(shí),介紹了第一類曲率算子和第二類曲率算子及Bochner Weitzenboch公式的相關(guān)問題,,并介紹了最近的研究工作相關(guān)進(jìn)展,。在本次演講中,李教授將簡要介紹第二類曲率算子,,并討論了Nishikawa-猜想的證明,。最后,他介紹了最近在第二類曲率算子負(fù)下界條件的新球面定理方面的工作和相關(guān)問題,。
李小龍教授的報(bào)告緊扣前沿,,開闊了在場學(xué)生的學(xué)術(shù)視野,提升了同學(xué)們的科研品味,。講座結(jié)束后,,李小龍教授在線與師生進(jìn)行交流互動(dòng),學(xué)院師生受益匪淺,。
