Hello,
Apologies there was crucial info missing in one of the home assignments ( proposition 1.1/slide 8)! Namely that the linear operator T from V to W is ‘one-to-one’. The updated slides available on GitHub.
I strongly encourage all those who are attending the live sessions or watching the youtube replays, to join our Gitter channel. It is where the post-session discussions happen and a great place to get help if you are stuck on something related to the sessions.
Happy weekend!:)
