Hi. I would like to ask some questions.
[About my background]
First of all I am new to GA. I am shocked with the powerfulness of GA/Clifford algebra.
My research has heavy geometric contents, I guess GA may be well-suited for that.
My research is about matrix factorizations, and especially the factorization of nonnegative matrices, which has a lot of geometry behind.
[The question]
From the GAME2020 videos (which are very good), I understand that, if x is inside the span(a_1,…,a_n), then it is equivalent to the wedge product x ^ (a_1 ^ … ^ a_n) = 0. But this is only saying "x is a linear combination of {a_i} ", what about affine combination? conical combination? convex combination?
Thank you very much
