I was odd to me to see that Ben Eater was involved. His talents are broad.
Is there such a thing as quaternion analysis -- calculus of functions from quaternions to quaternions.
What would be their key theorems ? What would be the analogue of conformal mappings, if any ?
Any book recommendations would be gratefully appreciated.
There are also these notes: https://www.geometrictools.com/Documentation/Quaternions.pdf
quat = sqrt( exp( nepers + radians * <axis> ) )
Thanks for your comment. To be fair, I had not done due diligence before asking. There's a Wikipedia pages on quaternion calculus.
Complex analysis (calculus on functions from 2D rotations to 2D rotations) is beautiful -- Once differentiability guarantees infinite differentiability. Wondering what would the analogue of that be for quaternions
