Cross subsidization is the practice of charging higher prices to one type of consumers to artificially lower prices for another group.State trading enterprises with monopoly control over marketing agricultural exports are sometimes alleged to cross subsidize, but lack of transparency in their operations makes it difficult, if not impossible, to determine if that is the case.
An example would be an increase in disposable income arising from a decrease in price of an essential good or service that the government has enforced in a form of monetary support. In contrast, a decrease in the price of a good or service may lead to an increase in revenue for producers earned from the heightened demand by consumers.
This page will attempt to list examples in mathematics. To qualify for inclusion, an article should be about a mathematical object with a fair amount of concreteness. Usually a definition of an abstract concept, a theorem, or a proof would not be an "example" as the term should be understood here (an elegant proof of an isolated but particularly striking fact, as opposed to a proof of a ...

In mathematics, the Kronecker product, sometimes denoted by ⊗, is an operation on two matrices of arbitrary size resulting in a block matrix.It is a specialization of the tensor product (which is denoted by the same symbol) from vectors to matrices and gives the matrix of the tensor product linear map with respect to a standard choice of basis.
Basic Linear Algebra Subprograms (BLAS) is a specification that prescribes a set of low-level routines for performing common linear algebra operations such as vector addition, scalar multiplication, dot products, linear combinations, and matrix multiplication.
Items of information a and b are known and are to be fused into information item c.We know a and b have mean/covariance ^, and ^, , but the cross correlation is not known. The covariance intersection update gives mean and covariance for c as
