Epic CEO Tim Sweeney might be one of the most outspoken people in the history of the world. He fought two of the world's most valuable and powerful companies almost all the way to the US Supreme Court, insulting them again and again: "crooked," "deceitful," "insanely sneaky," calling Android a "fake open platform," calling both companies "gangster-style businesses that will do anything they think they can get away with," telling me how Google's Project Hug was "an astonishingly corrupt effort at a massive scale.",详情可参考WPS下载最新地址

Definition 4 (Definition: Fundamental Group) Let \(X\) be a topological space and \(x_0 \in X\) a basepoint. A loop based at \(x_0\) is a continuous map \(\gamma: [0,1] \to X\) with \(\gamma(0) = \gamma(1) = x_0\). Two loops \(\gamma, \delta\) are homotopic relative to \(x_0\) (written \(\gamma \simeq \delta\)) if there exists a continuous map \(H: [0,1] \times [0,1] \to X\) such that \[H(s,0) = \gamma(s), \quad H(s,1) = \delta(s), \quad H(0,t) = H(1,t) = x_0\] for all \(s,t \in [0,1]\). This is an equivalence relation; denote the equivalence class of \(\gamma\) by \([\gamma]\).
