What is a curvelet transform? A curvelet is a mathematical building‑block, much like a wavelet but stretched, and directional, so it has an "orientation" that better represents images/signals which ...

The technology blockchain has established itself as a powerful tool in various sectors, and education is no exception. With its ability to offer security, transparency and decentralization, blockchain ...

I study automorphic forms, which lie at the intersection of number theory and harmonic analysis. In particular, I'm interested in the interplay between the Fourier theory of automorphic forms and the ...
