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 \(\bar\gamma(s) := \gamma(1-s)\).

第二百六十五条 保险标的在保险期间发生几次海上保险事故所造成的损失，即使损失金额的总和超过保险金额，保险人也应当赔偿。但是，对发生部分损失后未经修复又发生全部损失的，保险人按照全部损失赔偿。。体育直播对此有专业解读
Zaddy is an unfinished language for describing compilers. I shared notes on its design. Its full title is "META Restricted ACE Zaddy". By "ACE" I mean that Zaddy ought to match terms with respect to Associative and Commutative operators, as well as Equality of distinct terms. E-matching is a well-studied-enough problem that there is literature on it, but there is little progress on full ACE-matching. Previously, on Lobsters, I explained that finishing Zaddy is not something I would expect from a bot or from another human. But under the relaxed rules, why not give it a try?
