The IBS discrete mathematics group welcomes Dr. Abhishek Methuku, a new research fellow at the IBS discrete mathematics group from August 1, 2019.
He received his Ph.D. from the Department of Mathematics at the Central European University in Budapest, Hungary in 2019 under the supervision of Prof. Gyula O. H. Katona and Prof. Ervin Győri. Welcome!
On July 22, 2019, the 2019 IBS Summer Research Program on Algorithms and Complexity in Discrete Structures started at the IBS discrete mathematics group, running for three weeks in the summer.
On July 16, 2019, Dabeen Lee (이다빈) from IBS Discrete Mathematics Group presented his work on identifying a clutter minor related to ideal clutters at the Discrete Math Seminar. The title of his talk was “Integrality of set covering polyhedra and clutter minors”.
On June 25, 2019, Patrice Ossona de Mendez from CNRS, France presented a talk on the structural sparsity of graphs in terms of the model theoretic notion of first-order transduction. The title of his talk was “A model theoretical approach to sparsity”.
The IBS discrete mathematics group welcomes two new students.
Donggyu Kim (김동규) is a new graduate student from July 2019 and is currently a graduate student at the department of mathematical sciences, KAIST.
William Overman is a visiting student from June 2019 to August 2019 and is currently an undergraduate student in California Institute of Technology. His research visit is sponsored by his home university.
On June 19, 2019, Suil O (오수일) from SUNY Korea, Incheon presented his work on an upper bound of the third largest eigenvalue of a connected r-regular graph to have an odd (1,b)-factor. The title of his talk was “An odd [1,b]-factor in regular graphs from eigenvalues”.
