Thanks!
There are some videos missing in the playlist - could you please add them?
The definition of nondegeneracy in the theorem statement at 5:10 is incorrect. It should be that if x is nonzero then there exists some y such that K(x,y) is nonzero.
@21:51 I am sure I am missing something huge, but would somebody tell me why J is a solvable ideal of I perp if it commutes with it? (J can't be a center of I perp, as J isn't contained in I perp in the first place, I and I perp being a direct sum.)
we are so back
Simi 😅
simisimple?
Thumbnail much?
what does that mean
