안녕하세요, 6월 말부터 7월 초까지 짧게 있을 세미나를 소개드립니다. 7월 8일 ~ 7월 10일에는 Yangian의 표현을 배울 수 있는 QSMS Summer School이 있을 예정입니다. 자세한 정보는 아래 링크를 참조하세요 : https://sites.google.com/view/qsms2024ssrt https://sites.google.com/view/qsms2024ssrt Yangian의 대수 구조는 finite W-algebra, 그리고 quantum affine algebra와 깊은 관계를 가지고 있습니다. 따라서 QSMS Summer School 이전에 Yangian과 관련된 구조를 중심으로 finite W-algebra, quantum affine algebra를 공부하는 세미나를 진행하려 합니다. 세미나 정보는 다음과 같습니다 : 6월 24일 14:00 ~ 15:30 129동 309호, Finite W-algerba, 이강산6월 26일 14:00 ~ 15:30 129동 301호, Finite W-algerba., 윤상원7월 1일 14:00 ~ 15:30 129동 309호, Quantum affine algebra, 박민희7월 3일 14:00 ~ 15:30 129동 301호, Quantum affine algebra, 최동준세미나 주제에 관심이 있으신 분들께서는 자유롭게 참석 가능하시며, 궁금한 점이 있다면 제게 알려주시기 바랍니다. 감사합니다. 최동준 드림 I would like to introduce a short seminar series that will be held from late June to early July. From July 8 to July 10, the QSMS Summer School will take place, focusing on the representations of the Yangian. For more information, please visit : https://sites.google.com/view/qsms2024ssrt https://sites.google.com/view/qsms2024ssrt The algebraic structure of the Yangian is closely related to finite W-algebra and quantum affine algebra. Therefore, before the QSMS Summer School, we plan to hold seminars focusing on these related structures. The seminar details are as follows : June 24, 14:00 ~ 15:30, Room 309, Building 129, finite W-algebra, presented by 이강산June 26, 14:00 ~ 15:30, Room 301, Building 129, finite W-algebra, presented by 윤상원July 1, 14:00 ~ 15:30, Room 309, Building 129, quantum affine algebra, presented by 박민희July 3, 14:00 ~ 15:30, Room 301, Building 129, quantum affine algebra, presented by 최동준If you are interested in the seminar topics, please feel free to attend. If you have any questions, do not hesitate to contact me. Thank you. Best regards, Dong-Jun Choi

안녕하세요, 다음 주에 있을 세미나에 대한 안내를 드립니다. 두 가지 내용이 이전 메일에서 추가되었습니다. (1) 참고문헌을 알려달라는 요청이 있었습니다. 발표자분들께 참고문헌을 받아왔지만, 하나만의 참고문헌을 그대로 따라가는 방식의 세미나는 아닐 것 같으므로 참고만 해주시기 바랍니다. (2) 발표는 한국어로 진행됩니다. 발표 1 일시 : 6월 24일 월요일 14:00 - 15:30 장소 : 129동 309호 발표자 : 이강산 주제 : Finite W-algebra 참고문헌 : Shifted Yangians and finite W-algebras, Brundan-Kleshchev, 2006, Adv. in Math. 발표 2 일시 : 6월 26일 수요일 14:00 - 15:30 장소 : 129동 301호 발표자 : 윤상원 주제 : Finite W-algebra 참고문헌 : 1. Introduction to finite W-algebras, D.V.Artamonov 2. Finite vs affine W-algebra, De Sole, Kac 다음 주에 뵙겠습니다. 감사합니다. 최동준 올림 Dear all, I would like to inform you about the seminar that will take place next week. Two things have been added since the previous email. (1) There has been a request for references. Although I have collected references from the presenters, please note that the seminar will not follow a single reference. (2) The presentation will be given in Korean. Presentation 1 Date and Time : Monday, June 24th at 2:00PM to 3:30PM Venue : Building 129, Room 309 Presenter : 이강산 Topic : Finite W-algebra Reference :  Shifted Yangians and finite W-algebras, Brundan-Kleshchev, 2006, Adv. in Math. Presentation 2 Date and Time : Wednesday, June 26th at 2:00PM to 3:30PM Venue : Building 129, Room 301 Presenter : 윤상원 Topic : Finite W-algebra References : 1.

FW: Abstract for team seminar
by 최동준 20 Jun '24

20 Jun '24

Dear all, I am forwarding you the email I received from Léo. The informations of today's seminar are as follows :  Time : 15:30 ~ 17:30 Location : Room 309, Building 129 Best regards, Dong-Jun Choi -----Original Message-----From: "Léo Buisine" <leo.buisine.leo(a)gmail.com>To: "최동준" <djchoi9696@snu.ac.kr>;Cc:Sent: 2024-06-20 (목) 00:53:46 (UTC+09:00)Subject: Abstract for team seminar tomorrowDear 최동준,  Here is a title and an abstract for my talk tomorrow.  주제 : A journey through symmetries 초록 : This talk should serve as a (re)introduction to symmetries in physics. After a discussion on the structure of spacetime and on the phenomenology of symmetries in physics, we will study the structure of the Lorentz group and of the Poincare group. We will also see the notion of spinor, which will be useful in what follows. Then, we will discuss of the Coleman-Mandula theorem, and how to bypass it by considering fermionic generators. This will naturally lead to the supersymmetry algebra. Finally, we will see how supersymmetry simplifies in the context of conformal invariance, leading to a nice superconformal algebra and to the structure of supersymmetric vertex algebras.  참고문헌 :  Lectures on Supersymmetry, Matteo Bertolini Notes on Superconformal Representations in Two Dimensions, Siyul Lee and Sungjay Lee I am sorry for sending this so late, I forgot to send you an email yesterday. Best regards, Leo
