In mathematics, a singularity is in general a point at which a given mathematical object is not defined, or a point where the mathematical object ceases to be well-behaved in some particular way, such as the lack of differentiability or analyticity.

在数学中，<font color="#ff8000">奇点</font>一般是一个给定数学对象没有定义的点，或一个数学对象在某些特定方面不再表现良好的点，例如缺乏可微性或可分析性。

在x=0处有一个<font color="#ff8000"> 奇点 singularity</font>，在这里它似乎“爆炸”到±∞，因此没有定义。绝对值函数g（x）=| x |在x=0处也有奇点，因为它在那里不可微。

The algebraic curve defined by <math>\{(x,y):y^3-x^2=0\}</math> in the <math>(x, y)</math> coordinate system has a singularity (called a cusp) at <math>(0, 0)</math>. For singularities in algebraic geometry, see singular point of an algebraic variety. For singularities in differential geometry, see singularity theory.

在（x，y）坐标系中{（x，y）：y3−x2=0}定义的代数曲线在（0,0）处有一个奇点（称为尖点）。代数奇点的多样性，参见代数几何中的奇异点。关于微分几何中的奇点，见奇点理论

In real analysis, singularities are either discontinuities, or discontinuities of the derivative (sometimes also discontinuities of higher order derivatives). There are four kinds of discontinuities: type I, which has two subtypes, and type II, which can also be divided into two subtypes (though usually is not).

在实际分析中，<font color="#ff8000">奇点</font>要么是不连续的，要么是导数的不连续（有时也是高阶导数的不连续）。有四种不连续性：I型，有两种亚型；II型，也可分为两种亚型（尽管通常不是）。
does not tend towards anything as <math>x</math> approaches <math>c = 0</math>. The limits in this case are not infinite, but rather undefined: there is no value that <math>g(x)</math> settles in on. Borrowing from complex analysis, this is sometimes called an essential singularity.

不倾向于做任何事情，因为。在这种情况下，极限不是无限的，而是未定义的: 没有一个值是g (x)确定的。借用复杂的分析，这有时被称为本质奇点。
