product introduction
31Natural product drug discovery — This article describes the utilization of natural resources in the process of finding new drug compounds, an approach commonly referred to as natural product drug discovery . Together with synthetic chemistry, they represent complementary… …
32Collaborative product development — (collaborative product design) (CPD) is a business strategy, work process and collection of software applications that facilitates different organizations to work together on the development of a product. It is also known as collaborative product …
33Lie product formula — In mathematics, the Lie product formula, named for Sophus Lie, states that for arbitrary n × n real or complex matrices A and B, where eA denotes the matrix exponential of A. The Lie–Trotter product formula (Trotter 1959) and the Trotter–Kato… …
34Inner product space — In mathematics, an inner product space is a vector space with the additional structure of inner product. This additional structure associates each pair of vectors in the space with a scalar quantity known as the inner product of the vectors.… …
35Triple product — This article is about the mathematical product. For the product in nuclear fusion, see Lawson criterion. In mathematics, the triple product is a product of three vectors. The name triple product is used for two different products, the scalar… …
36Gross domestic product — GDP redirects here. For other uses, see GDP (disambiguation). Not to be confused with Gross national product or Gross domestic income. CIA World Factbook 2005 figures of total nominal GDP (top) compared to PPP adjusted GDP (bottom) …
37Kronecker product — In mathematics, the Kronecker product, denoted by otimes, is an operation on two matrices of arbitrary size resulting in a block matrix. It is a special case of a tensor product. The Kronecker product should not be confused with the usual matrix… …
38Zero-product property — In the mathematical areas of algebra and analysis, the zero product property, also known as the zero product rule , is an abstract and explicit statement of the familiar property from elementary mathematics that if the product of two real numbers …
39Tensor product of fields — In abstract algebra, the theory of fields lacks a direct product: the direct product of two fields, considered as a ring is never itself a field. On the other hand it is often required to join two fields K and L, either in cases where K and L are …
40Topological tensor product — In mathematics, there are usually many different ways to construct a topological tensor product of two topological vector spaces. For Hilbert spaces or nuclear spaces there is a simple well behaved theory of tensor products (see Tensor product of …
