| Sep 17, 2023 at 20:50 | comment | added | YCor | You'd need to make the question more precise. A quadratic algebra is by definition graded, so you should take a graded subalgebra for the question to make sense — but then taking a graded subalgebra not generated in degree 1 easily answers. Otherwise, you might mean "an algebra that admits a grading which make it a quadratic algebra" (this is not the same!) and then the question makes sense for subalgebras. Then there are easy examples anyway. | |
