Inverse or inversion or similar may refer to:
- Inverse (logic), a type of immediate inference from a conditional sentence In grammar, conditional sentences are sentences discussing factual implications or hypothetical situations and their consequences. Languages use a variety of conditional constructions and verb forms to form these kinds of sentences
- Multiplicative inverse In mathematics, a multiplicative inverse or reciprocal for a number x, denoted by 1⁄x or x −1, is a number which when multiplied by x yields the multiplicative identity, 1. The multiplicative inverse of a fraction a⁄b is b⁄a. For the multiplicative inverse of a real number, divide 1 by the number. For example, the reciprocal of 5 is one
- Inverse (program), a program for solving inverse and optimization problems
- Inversion (music) In music theory, the word inversion has several meanings. There are inverted chords, inverted melodies, inverted intervals, and inverted voices. The concept of inversion also plays a role in musical set theory
- Inversion (prosody), the reversal of the order of a foot's elements
- Inversion (linguistics) In linguistics, grammatical inversion is any of a number of different distinct grammatical constructions in the languages of the world. There are three main uses in the literature which, unfortunately, have little if any overlap either formally or typologically: syntactic inversion, thematic inversion, and feature inversion
- Inversion (law), reincorporation by a firm in a different country e.g. to save taxes
- Inversion in postcolonial theory, a discursive strategy/gesture in cultural and subaltern studies
- Invert, a BMX trick
- Inverted pyramid The inverted pyramid is a metaphor used by journalists and other writers to illustrate the placing of the most important information first within a text. It is the most widely preferred method in writing news stories.[citation needed], a way to arrange information in a news story
- Inverted sugar syrup
- Anastrophe Anastrophe is a figure of speech involving an inversion of a language's ordinary order of words; for example, saying "echoed the hills" to mean "the hills echoed". In English, with its settled natural word order, departure from the expected word order emphasizes the displaced word or phrase: "beautiful" is emphasized, a literary device
- Mirror image A mirror image is a reflected duplication that appears identical but in reverse. As an optical effect it results from reflection off of substances such as a mirror or water. It is also a concept in geometry and can also be used in a conceptualization process for 3-D structures
- An ambigram An ambigram is a typographical design or artform that may be read as one or more words not only in its form as presented, but also from another viewpoint, direction, or orientation. The words readable in the other viewpoint, direction or orientation may be the same or different from the original words. Douglas R. Hofstadter describes an ambigram (inversion was a common term before the word ambigram was coined)
- Roller coaster inversions, which turn riders upside-down
- Inversion therapy, the practise of hanging upside down (heart higher than head) for supposed health benefits.
- "invert" may be used by naturalists as short for "invertebrate An invertebrate is an animal without a backbone. The group includes 95% of all animal species — all animals except those in the chordate subphylum Vertebrata"
Science and mathematics
- Inversion (kinesiology), movement of the sole towards the median plane
- Inverse (mathematics)
- Inversive geometry, transformation geometry based on inversion in a circle
- Method of inversion, the image of a harmonic function in a sphere (or plane).
- Inverse problem An inverse problem is the task that often occurs in many branches of science and mathematics where the values of some model parameter must be obtained from the observed data, in science and mathematics, fitting a model to known data
- Inversion (geology), the relative uplift of a previously basinal area resulting from local shortening, in structural geology
- Inversion (meteorology) In meteorology, an inversion is a deviation from the normal change of an atmospheric property with altitude. It almost always refers to a temperature inversion, i.e., an increase in temperature with height, or to the layer within which such an increase occurs, air temperature increasing with height
- Inversion (nuclear), the "island of inversion", a group of elements with abnormal nuclear shell structure
- Chromosomal inversion, where a segment of a chromosome is reversed end to end
- Inversion (evolutionary biology), a hypothesis about the evolution of the dorsoventral axis in animals
- Nitrogen inversion In chemistry, a nitrogen compound like ammonia in a trigonal pyramid geometry undergoes rapid nitrogen inversion whereby the molecule turns inside out. This interconversion is a room temperature process because the energy barrier is relatively small. Contrast this to phosphine which does not show inversion at room temperature (energy barrier: 132, a chemical process in which a trigonal nitrogen-containing structure turns inside-out
- Population inversion, in statistical mechanics, when a system exists in state with more members in an excited state than in lower energy states
- Sexual inversion, in biology, the switching from one sex to the opposite among some animal species.
- Sexual inversion (sexology), a term for reversal of gender roles, usually implying homosexuality, found primarily in older scientific literature
- Inversion (linguistics) In linguistics, grammatical inversion is any of a number of different distinct grammatical constructions in the languages of the world. There are three main uses in the literature which, unfortunately, have little if any overlap either formally or typologically: syntactic inversion, thematic inversion, and feature inversion, a term referring to a number of different distinct grammatical constructions found in the languages of the world.
Computer science
- Priority inversion, in which a low-priority task holds a shared resource that a high-priority task needs
- Inversion (computer science), items that are out of order in a list
Technology
- Inverse multiplexer (or 'demultiplexer'), which breaks a single data stream into several streams with lower data rates
- Inverter (electrical) An inverter is an electrical device that converts direct current to alternating current (AC); the converted AC can be at any required voltage and frequency with the use of appropriate transformers, switching, and control circuits, which converts direct current to alternating current
- Inverter (logic gate) (or 'NOT gate')
- Inverted flight, flying upside down
- Invert, the base of a tunnel on which the road or railway may be laid. It may be flat or form a continuous curve with the tunnel arch. [1]

- Inversions (novel) by Iain M Banks
- Inversions, an art book published in 1981, written by puzzle designer Scott Kim

How to find the inverse of a matrix containing complex imaginary numbers?
Q. Is the method for doing this the same as if the matrix contained real numbers? This is how I would find the inverse of a matrix with real numbers A. Make the augmented matrix [A|I] and then use row reduction to change it to [I|B] B being the inverse of A. Basically my question is, can you do this with imaginary complex numbers?

A. Yes. Imaginary and complex numbers obey the same rules of arithmetic as real numbers.
