Constructing $X$ with $π_1(X) ≅ ℝ$

84 Views Asked by At

Let $X$ be a connected CW-complex with $π_1(X) ≅ ℝ$, $π_n(X) ≅ 0$ for $n ≥ 2$.

Can someone help me obtain a description or construction of $X$?

$ΩX$ has connected components in correspondence with $ℝ$, but also the group structure should match as well.
