称 A 是\mathcal{C} 中的“余单点对象 (cosingleton object)”,如果 A 不是terminal object,且对任何 \mathcal{C} 中的非terminal的object B 及任何morphism f:A\to B ,都有 f 是monomorphism. 在这个框架下,上面的性质简述为 在范畴 \mathbf{CRing} 中,一个object是域当且仅当它是余单点对象。
1. "Solving quadratic equations is considered trivial for most math majors."(对于大多数数学专业的学生来说,解二次方程是一件显而易见的事情。) 2. "The professor explained the profoundconcept in such a trivial manner that everyone understood it."(教授以如此简明的方式解释了那个深奥的概念,以至于每个...

For our player, the math behind it is not as important as the experience. That experience informs their mind-set, which informs their choices, which folds back in on their experience. Yes, that is a conceptual cluster-fuck, but we’re self-aware beings, so you weren’t expecting an easy...
