## inverse

### 語源

Recorded since 1440, from Latin inversus, the past participle of invertere (), itself from in- (in, on) + vertere ().

### 発音

• (General American) IPA(key): /ɪnˈvɝs/, /ˈɪnvɝs/

### 名詞

inverse (複数形 inverses)

1. An inverted state: a state in which something has been turned (properly) upside down or (loosely) inside out or backwards.

321 is the inverse of 123.
2. The result of an inversion, particularly:

3. (geometry) The result of a circle inversion; the set of all such points; the curve described by such a set.
The inverse P‘ of a point P is the point on a ray from the center O through P such that OP × OP = or the set of all such points.
4. (logic) The non-truth-preserving proposition constructed by negating both the premise and conclusion of an initially given proposition.
"Anything that isn't a dog doesn't go to heaven" is the inverse of "All dogs go to heaven." More generally, ${\displaystyle \lnot {\mathsf {p}}\to \lnot {\mathsf {q}}}$ is the inverse of ${\displaystyle {\mathsf {p}}\to {\mathsf {q}}}$ and is equivalent to the converse proposition ${\displaystyle {\mathsf {q}}\to {\mathsf {p}}}$.
• 1896, James Welton, A Manual of Logic, 2nd ed., Bk iii, Ch. iii, §102:
Inversion is the inferring, from a given proposition, another proposition whose subject is the contradictory of the subject of the original proposition. The given proposition is called the Invertend, that which is inferred from it is termed the Inverse... The rule for Inversion is: Convert either the Obverted Converse or the Obverted Contrapositive.
3. (mathematics) A second element which negates a first; in a binary operation, the element for which the binary operation—when applied to both it and an initially given elementyields the operation's identity element, specifically:
1. (addition) The negative of a given number.
The additive inverse of ${\displaystyle x}$ is ${\displaystyle -x}$, as ${\displaystyle x-x=0}$, as ${\displaystyle 0}$ is the additive identity element.
2. (multiplication) One divided by a given number.
The multiplicative inverse of ${\displaystyle x}$ is ${\displaystyle x^{-1}}$, as ${\displaystyle x\times x^{-1}=1}$, as ${\displaystyle 1}$ the multiplicative identity element.
3. (functions) A second function which, when combined with the initially given function, yields as its output any term inputted into the first function.
The compositional inverse of a function ${\displaystyle f}$ is ${\displaystyle f^{-1}}$, as ${\displaystyle f\ f^{-1}={\mathit {I}}}$, as ${\displaystyle {\mathit {I}}}$ is the identity function. That is, ${\displaystyle \forall x,f(f^{-1}(x))={\mathit {I}}(x)=x}$.
4. (category theory) A morphism which is both a left inverse and a right inverse.
5. (card games) The winning of the coup in a game of rouge et noir by a card of a color different from that first dealt; the area of the table reserved for bets upon such an outcome.
