Let C be the wedge of countably many circles.

1) Which of these 3 spaces are CW complexes?

2) Attempt to construct contiinuous bijectiive maps between these spaces (if possible) & then show if these are homeomorphisms.

3) Are the any other more "immediate" way of showing any of the spaces are homeomorphic?

I'm completely stuck! :-( Any assistance would be ENORMOUSLY helpful!

Thanks in advance. :-) x
