Part of the beauty of this film is where Jarmusch leaves each story. He's rarely been one for buttoned-up conclusions. And here, he essentially offers not even a day, but a few hours in the lives of people bound by blood, and — what else? We get a window into their lives, and a glimpse of how they see each other. Then, their story moves on without us. Where will they go? What will they experience? It's a mystery the movie won't dwell on, but we can.
The fundamental group of \(X\) at \(x_0\) is \[\pi_1(X, x_0) \;:=\; \bigl\{[\gamma] \mid \gamma \text{ is a loop based at } x_0\bigr\}\] equipped with the group operation of concatenation: \[[\gamma] \cdot [\delta] := [\gamma * \delta], \qquad (\gamma * \delta)(s) := \begin{cases} \gamma(2s) & s \in [0,\tfrac{1}{2}] \\ \delta(2s-1) & s \in [\tfrac{1}{2},1] \end{cases}\] The identity element is the class of the constant loop \([c_{x_0}]\), and the inverse of \([\gamma]\) is \([\bar\gamma]\) where \(\bar\gamma(s) := \gamma(1-s)\).
