1) Give as many examples as you can of topological groups which do not fall within any of the examples we gave in section Functional Analysis 9.1.

2) Prove that the inverse of an isomorphism.

3) show that for each ${\displaystyle x\in G}$ the maps ${\displaystyle L_{x}(y)=xy}$ and ${\displaystyle R_{x}(y)=yx}$ are topological group homomorphisms.

4)
