Professor JungHwan Park and Dr. Sungkyung Kang’s work featured by Quanta

Professor Park and Dr. Kang’s recent article “The (2,1)-cable of the figure-eight knot is not smoothly slice” was featured in Quanta magazine. The work is joint with Irving Dai, Abhishek Mallick, and Matthew Stoffregen. Sungkyung Kang got a bachelor degree in 2014 and a master’s degree in 2015 from our department. They answer a forty-year-old question posed by Akio Kawauchi, a emeritus professor at the Osaka City University.
