around 17:00 , the last term was 0 not by dimensional reason. It was 0 for precisely the same reason as the first term. Basically, every third term in the exact sequences of triples are 0.
I believe that in the very end, σ and b need not be simplicies themselves. In general, I think, they are finite sums of simplicies with integer coefficients, but since the sums are finite, we can take the maximum n that is hit, over all simplicies involved. Amazing lecture! Thanks!
Great lecture series ever I had.I got clear understanding.Hats off to this professor

This series is great, can't wait for cohomology related lectures!

The topic is difficult as it is, and the professor constantly stumbling and giving incorrect arguments doesn't help.
Where exactly did he give an incorrect argument?
