## Contents

Read section 11 of chapter II and sections 1-3 of chapter V of Bredon's book three times:

• Second time like you were studying for an exam on the subject - slowly and not skipping anything, verifying every little detail.
• And then a third time, again at a quicker pace, to remind yourself of the bigger picture all those little details are there to paint.

## Doing

Solve the following problems from Bredon's book, but submit only the solutions of the problems marked with an "S":

## Just for Fun

Find a geometric interpretation to the formula

$d\omega(X,Y)=X(\omega(Y))-Y(\omega(X))-\omega([X,Y])$.

(Of course, you have to first obtain a geometric understanding of $[X,Y]$, and this in itself is significant and worthwhile).

Look at the story of Barnie the polar bear.
