Is the Laplace eigenbasis considered a basis in a relaxed sense that permits non-orthogonality or does the notion of orthogonality itself change to counteract the apparent redundancy?
- Twisol 6y agoBases only need to be linearly independent and spanning; non-orthogonality is already permitted. Not all bases are orthogonal.
- jjoonathan 6y agoRight, thanks, it's been too long.
