@AlexKontorovich Reminds me of an argument I’ve seen in the past (I won’t say who proposed it) that humans will always have the edge over computers at maths because we can think about infinite sets.

[New] Hard Instances of Discrete Logarithm Problem and Cryptographic Applications (Christopher Battarbee and Arman Darbinyan and Delaram Kahrobaei) ia.cr/2025/1461

Queens College, City University of New York, is hiring a tenure-track Assistant Professor in Computer Science. The position is open until filled, with review of applications beginning September 28, 2025. Apply here: cuny.jobs/queens-ny/assi…

Our surprising result joint with Arman Darbinyan and Christopher Battarbee: There exist infinite groups in which the Discrete Logarithm Problem is NP-complete. #PQC Grateful for the support of @Institut_IHES @InHenriPoincare where this research began. arxiv.org/abs/2508.08823

Thinking of the lovely time I had in Israel a decade ago with the warm hospitality of Israeli friends I made throughout the years. Looking forward to visiting this beautiful country again.

IHES is celebrating the five-year anniversary of the Gretchen and Barry Mazur Chair! For the anniversary of the Chair, IHES has made Oliver Ralfe’s intimate documentary, “Barry Mazur and the Infinite Cheese of Knowledge,” available on its YouTube channel. youtu.be/bEf26NFur3w?si…

IHES podcast recommendation: @franceculture has just released an excellent series of podcasts (in French) by Marie Durrieu on the life and work of Alexander Grothendieck who was a Permanent Professor in Mathematics at IHES from 1958 to 1970. radiofrance.fr/franceculture/…

When I say that Bitcoin is a currency of distrust, I'm just repeating what Bitcoin fans themselves say. There may be good reasons not to trust the banks and governments that create dollars, yens, and other currencies – but that doesn’t change the fact that the preference for Bitcoin is based on distrust of human institutions. Why is this an alarming development? Because the whole purpose of money is to create trust between strangers. Financial devices like currencies, bonds and shares – 90% of which are just data in computers – build trust between millions of strangers, who can then pool their knowledge and resources together, and cooperate. Humans control the world because we learned to do this. If we now lose trust in human institutions, this will limit the amount of money and handicap economic activity and cooperation. I hope that humanity finds a way to build trustworthy human institutions, instead of adopting technologies of distrust. #bitcoin #trust #distrust #crypto #currency #humanity #institutions #money #finance

IHES is greatly saddened by the news of Jim Simons’ passing. Jim first visited IHES in the 70s & stayed very close to the Institute ever since. His support of IHES through @SimonsFdn has been completely transformative & unparalleled. ihes.fr/en/tribute-to-…

We mourn the loss of our friend and founding benefactor, Jim Simons. Jim was visionary, brilliant, and generous beyond measure. He has left an indelible mark on our field.

This week at AIM: Post-quantum group-based cryptography.
