On this page I might occasionally write down some of my thoughts,
although the topics could differ between all of my interests.
In this short note we try to find radical isogenies on twisted Edwards curves. We will do so by first looking at what radical isogenies are, and then look at how radical isogenies should work on twisted Edwards curves. Finally, by firing up a computer algebra system, we find the concrete radical isogeny formula forContinue reading “Radical isogenies on (twisted) Edwards curves”
Our concept of trust is about to change. The recent rise of deepfakes, highly convincing fake audio or video files that are manipulated using machine learning techniques, is deeply disturbing and will have a high impact on what is meant by trust in the near future. How do we decide what is real and what is fake? WillContinue reading “Deepfakes and digital signatures”
One of the main themes in Kendrick Lamar’s tour de force King Kunta is ‘the yam’. If you are wondering what the yam is, and what it represents, you don’t have to look far for an answer: we find both the question and the answer in the lyrics. What’s the yams? The yam is theContinue reading “How Kendrick Lamar and W.B. Yeats are connected through Chinua Achebe’s yams”
I’ve recently learned the possible name of a subject that I’ve always been interested in: Pythagorean Arithmetic. In short, this involves ‘proving’ theorems in number theory using mathematical thinking from approximately the 6th century BC, involving for the most very visual proofs, which can be explained using pebbles on a sandy beach. I write ‘proving’Continue reading “Pythagorean Arithmetic”
