In mathematics, especially in linear algebra and matrix theory, the duplication matrix and the elimination matrix are linear transformations used for transforming half-vectorizations of matrices into vectorizations or (respectively) vice versa.
For example, for the 2×2 matrix = [], the half-vectorization is = []. There exist unique matrices transforming the half-vectorization of a matrix to its vectorization and vice versa called, respectively, the duplication matrix and the elimination matrix .
Other examples include Log Cabin Republicans, [4] female criminality, [5] and African-American Muslim women. [6] One of the key concepts of the matrix of domination is that the different categories, like race and gender, are separate groups, rather than a combination.
Multiple jeopardy and intersectionality are two related but distinct frameworks that are often confused. While intersectionality, coined by Dr. Kimberlé Crenshaw, describes how different identity factors such as race, gender, and class intersect to create unique forms of discrimination, [5] multiple jeopardy — introduced by Dr. Deborah K. King — focuses specifically on the multiplicative ...
Duplication, or doubling, multiplication by 2; Duplication matrix, a linear transformation dealing with half-vectorization; Doubling the cube, a problem in geometry also known as duplication of the cube; A type of multiplication theorem called the Legendre duplication formula or simply "duplication formula"
Transformation: deleting/changing the cultural identities of people (examples include American Indian boarding schools). Repression: systematically limiting the power of the target group through political disenfranchisement , ghettos, enslavement , segregation , or other legal means (examples include anti-Jewish legislation in pre-war Nazi ...
Manifest functions are the consequences that people see, observe or even expect. It is explicitly stated and understood by the participants in the relevant action. The manifest function of a rain dance, according to Merton in his 1957 Social Theory and Social Structure, is to produce rain, and this outcome is intended and desired by people participating in the ritual.
An elimination order guarantees that a monomial involving any of a set of indeterminates will always be greater than a monomial not involving any of them. A product order is the easier example of an elimination order. It consists in combining monomial orders on disjoint sets of indeterminates into a monomial order on their union.
