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 \([\gamma]\).

That’s helpful for me here, though, because it means that I already have a bunch of routines handy that will do things like compute where, exactly, on the screen the cell is corresponding to the move the player just made, and it also means that the rest of the game logic is already such that I can rely on screen memory holding the most up-to-date information I need.
Исполнительный комитет организации напомнил о нейтралитете олимпийского движения. «Это лежит в самой основе олимпийского движения и вытекает из основополагающих принципов олимпизма», — отметили в МОК.
Escaping the guest kernel requires finding a vulnerability in the Virtual Machine Monitor’s device emulation or the CPU’s virtualization features, which are rare and highly prized.
