RT7.3. Finite Abelian Groups: Convolution

Representation Theory: We define convolution of two functions on L^2(G) and note general properties. Three themes: convolution as an analogue of matrix multiplication, convolution with character as an orthogonal projection on L^2(G), and using using convolution to project onto irreducible types in representations.

These videos are amazing! I absolutely love how students at different levels can learn something out of these. I find that professors too often use the phrase "this is trivial" (and that might be the case...) and it's just so difficult to follow them.

I had no idea Henry Rollins was so good at math.
