As part of the University Lecture Series, the University of Macau (UM) held a talk titled ‘Geometry Is a Singular Subject’ today (7 November). Richard Schoen, a world-leading mathematician and Excellence in Teaching Chair at the University of California at Irvine, was the speaker. Speaking at the event, Michael Hui, vice rector of UM, said that Prof Schoen is an expert in differential geometry and the mathematical theory of general relativity, adding that singularity is of great significance to research on differential geometry. During the talk, Prof Schoen discussed how singularity, a concept in mathematics, is applied in a significant amount of current research in differential geometry, encompassing topics ranging from corners which arise in optimal networks to black holes in general relativity. In addition, Prof Schoen actively engaged with the participants during the Q&A and discussion session.
澳門大學今（7）日舉行“大學講壇”講座，由世界頂尖數學家、加州大學歐文分校卓越教學講席教授理查德．舍恩就“幾何是一門奇點的學科”為題發表演說，探討當前微分幾何領域當中大部分研究與數學家所稱的奇點。
澳大副校長許敬文表示，理查德．舍恩是數學領域的傑出人物，他的專長包括微分幾何和廣義相對論的數學理論，在學術界享有崇高地位；奇點在當前微分幾何研究中具有重要意義。
講座上，理查德．舍恩指出奇點的概念涵蓋了從最優網路中出現的角點到廣義相對論中的黑洞，揭示了當前微分幾何研究與數學家所稱的奇點之間的關係。舍恩亦詳細探討了奇點在具體實例中的形態，揭示了奇點的神秘性質、分類及它們在微分幾何研究中的應用和重要性。問答及交流環節由澳大科技學院講座教授、數學系系主任桂長峰主持；舍恩與與會者交流互動，討論氣氛熱烈。
理查德．舍恩是世界知名數學家、美國國家科學院院士、美國科學促進會會士和美國數學會會士，在學術界享有崇高地位，並曾獲美國數學會波赫獎、古根海姆獎、沃爾夫數學獎等殊榮。
