We know a continuous bijection from a compact space to a Hausdorff space is always a homeomorphism.
But I am wondering what happens if we switch the domain and codomain. Is a continuous bijection function from a Hausdorff space to a compact space a homeomorphism?
What I think this is not true. Consider the example f:R→[−π2,π2] defined by f(x)=tan(x), then f is a continuous bijection but f−1 is not continuous.
Am I right? Thank you for any comments.
