Complex Grassmannians in the wild
#math #signalprocessing #manifold #optimization
There is a neat approach to wireless communication based on Grassmann manifolds over the field of complex numbers. It's an idea about 20 years old and it's easy to explain. Here is how it goes:

Long time ago a friend asked me to finish article that was started by his student. That's how I learned about octonions and exceptional Lie groups. mostly from the go to introductory text by John Baez. Now, around 15 years later, I was able to actually answer a question of Baez.

I made a Starter Pack for #MathSky, since the one @tienchihmath.bsky.social made (go.bsky.app/66Us7WW), is at max capacity. But I need your help! Let's crowdsource this to make it better. Reply with suggestions. **Please don't feel shy to self-nominate!**
