# Notice on POW 2024-05 and POW 2024-06

It is found that there is a flaw in POW 2024-05; some students showed that the collection of all Knotennullstelle numbers is not a discrete subset of $$\mathbb{C}$$. We again apologize for the inconvenience.

To acknowledge the students who reported the flaws in POW 2024-05 and POW 2024-06, we decided to give credits to 김준홍 (KAIST 수리과학과 20학번, +4) and 지은성 (KAIST 수리과학과 20학번, +3) for POW 2024-05 and Anar Rzayev (KAIST 전산학부 19학번, +4) for POW 2024-06.

Here is a “solution” of problem 2024-05.

# POW 2024-06 Canceled

It is found that there is a flaw in POW 2024-06; the inequality in the problem is not satisfied with the given g(t). Since it is too late to revise the problem again with a new deadline, we decide to cancel POW 2024-06. We apologize for the inconvenience.
