Jaehoon Kim (김재훈) gave a talk on a sufficient condition for a 2-complex to have a unique embedding in a 3-dimensional space, which is a 3-dimensional analog of Whitney’s theorem on the uniqueness of planar embeddings of a 3-connected graph at the Discrete Math Seminar

On November 9, 2021, Jaehoon Kim (김재훈) from KAIST gave a talk at the Discrete Math Seminar on a 3-dimensional analog of Whitney’s theorem on the uniqueness of planar embeddings of a 3-connected graph. The title of his talk was “2-complexes with unique embeddings in 3-space“.

Jaehoon Kim (김재훈) gave a talk on a resilience version of Pósa’s theorem regarding Hamiltonian cycles at the Discrete Math Seminar

On June 23, 2020, Jaehoon Kim (김재훈) from KAIST presented his work with Padraig Condon, Alberto Espuny Diaz, Daniela Kühn and Deryk Osthus on a resilience version of Pósa’s theorem regarding a sufficient condition on the degree sequence for a graph to have a Hamiltonian cycle at the Discrete Math Seminar. The title of his talk is “A resilience version of Pósa’s theorem“.
