Congratulations Dong Yeap Kang (강동엽) for receiving the Sangsan Prize for Young Mathematicians (상산젊은수학자상) from the Korean Mathematical Society

Our former member, Dr. Dong Yeap Kang (강동엽), has been selected as one of the three winners of this year receiving the Sangsan Prize for Young Mathematicians (상산젊은수학자상) from the Korean Mathematical Society. This prize is for those with outstanding academic achievements in mathematics who are within 5 years of receiving their Ph.D. degree. Dr. Kang was a research student of the IBS Discrete Mathematics Group and received his Ph.D. in 2020 from KAIST under the supervision of Sang-il Oum. He was a postdoctoral researcher at the University of Birmingham for 3 years and currently, he is a Young Scientist Fellow at the IBS Extremal Combinatorics and Probability Group. The award ceremony will be held on October 27, 2023 at the Seoul National University during the 2023 KMS Annual Meeting. Congratulations!

The 2023 Vertex-Minor Workshop was held from October 15 to 20 at Jeju

The 2023 Vertex-Minor Workshop was held from October 15, 2023 to October 20, 2023 at SONO Belle Jeju in Korea. This workshop aimed to foster collaborative discussions and explore the various aspects of vertex-minors, including structural theory and their applications. There were 17 participants from Korea, Italy, UK, Australia, Japan, and China and participants had great time to discuss open problems related to the vertex-minors of graphs.

Talks

  • October 16: Sang-il Oum, Survey of vertex-minors
  • October 17: O-joung Kwon, The grid theorem for vertex-minors
  • October 17: James Davies, Vertex-minors and preparing graph states
  • October 17: Paul Wollan, Flat-wall theorem for vertex-minors

Welcome Ruonan Li and Laihao Ding, long-term visitors to the IBS Extremal Combinatorics and Probability Group

The IBS Discrete Mathematics Groupo welcomes Laihao Ding and Rounan Li, two long-term visitors to the IBS Extremal Combinatorics and Probability Group.

Ruonan Li is an associate professor at Northwestern Polytechnical University, China. She arrived at IBS on September 29, 2023 and will stay with us until September 28, 2024.

Laihao Ding is a lecturer at Central China Normal University. He arrived at IBS on October 5, 2023 and will stay with us for 1 year.

Donggyu Kim (김동규) gave a talk on defining orthogonal matroids (or even delta-matroids) over tracts at the Discrete Math Seminar

On September 19, 2023, Donggyu Kim (김동규) from KAIST and the IBS Discrete Mathematics Group gave a talk at the Discrete Math Seminar on defining orthogonal matroids (or, equivalently even delta-matroids) over tracts and its applications to several theorems regarding representability. The title of his talk was “Orthogonal matroids over tracts.”

We are hiring: The IBS Discrete Mathematics Group (DIMAG) Research Fellowship (Due: Dec. 3, 2023)

The IBS Discrete Mathematics Group (DIMAG, https://dimag.ibs.re.kr/) in Daejeon, Korea invites applications for three research fellowship positions.

DIMAG is a research group that was established on December 1, 2018 at the Institute for Basic Science (IBS), led by Prof. Sang-il Oum. DIMAG is located at the headquarters of the Institute for Basic Science (IBS) in Daejeon, South Korea, a city of 1.5 million people.

Currently, DIMAG consists of researchers from various countries such as Korea, the USA, Germany, Canada, and Australia, and the work is done in English. DIMAG is co-located with the IBS Extremal Combinatorics and Probability Group (ECOPRO).

Successful candidates for research fellowship positions will be new or recent Ph.D.’s with outstanding research potential in all fields of discrete mathematics with emphasis on structural graph theory, combinatorial optimization, matroid theory, and algorithms.

These appointments are for about two years, and the starting salary is no less than KRW 59,000,000. The appointment is one-time renewable up to 5 years in total contingent upon the outstanding performance of the researcher. The expected appointment date is September 1, 2024, but it is negotiable within the same calendar year.

These are purely research positions and will have no teaching duties.

A complete application packet should include:

  1. AMS standard cover sheet (preferred) or cover letter (PDF format)
  2. Curriculum vitae including a publication list (PDF format)
  3. Research statement (PDF format)
  4. Application for the IBS & Consent to Collection and Use of Personal Information (PDF file)
  5. At least 3 recommendation letters

For full consideration, applicants should email items 1, 2, 3, and 4 and arrange their recommendation letters emailed to dimag@ibs.re.kr by December 3, 2023, Sunday. (Anywhere on Earth)

Recommendation letters forwarded by an applicant will not be considered.

DIMAG encourages applications from individuals of diverse backgrounds.

For Korean citizens who have not yet completed their military duty: 전문연구요원 종사를 희망하는 경우에는 지원 의사와 병역 관계를 cover letter 및 이메일 등에 표시하여 제출 필요. 다만 현역입영대상자의 전문연구요원 신규 편입은 불가하며, 보충역 대상자 및 타 기관에서 전직해서 오는 경우에 한하여 지원 가능(반드시 타 기관에서 전직 요건이 충족되는 등 전직 요건이 충족 되어야만 함)

Seog-Jin Kim (김석진) gave a talk on the list chromatic number of the square of subcubic planar graphs of girth at least 6 at the Discrete Math Seminar

On September 12, 2023, Seog-Jin Kim (김석진) from Konkuk University gave a talk at the Discrete Math Seminar on the list chromatic number of the square of subcubic planar graphs of girth at least 6. The title of his talk was “The square of every subcubic planar graph of girth at least 6 is 7-choosable“.
