Projected dynamical systems is a mathematical theory investigating the behaviour of dynamical systems where solutions are restricted to a constraint set. The discipline shares connections to and applications with both the static world of optimization and equilibrium problems and the dynamical world of ordinary differential equations .
Descartes' quantity of motion was different from momentum, but Newton defined the quantity of motion as the conjunction of the quantity of matter and velocity in Definition II of his Principia. In Definition III, he defined the force that resists a change in motion as the vis inertia of Descartes.
Muirhead's inequality states that [ a] ≤ [ b] for all x such that xi > 0 for every i ∈ { 1, ..., n } if and only if there is some doubly stochastic matrix P for which a = Pb . Furthermore, in that case we have [ a] = [ b] if and only if a = b or all xi are equal. The latter condition can be expressed in several equivalent ways; one of them ...
Structural inequality occurs when the fabric of organizations, institutions, governments or social networks contains an embedded bias which provides advantages for some members and marginalizes or produces disadvantages for other members. This can involve property rights, status, or unequal access to health care, housing, education and other ...

Law portal. v. t. e. Child pornography (also called CP, child sexual abuse material, [1] CSAM, [2] child porn, or kiddie porn) is erotic material that depicts persons under the age of 18. The precise characteristics of what constitutes child pornography varies by criminal jurisdiction. [3] [4] Child pornography is often produced through online ...
In mathematical logic and type theory, the λ-cube (also written lambda cube) is a framework introduced by Henk Barendregt [1] to investigate the different dimensions in which the calculus of constructions is a generalization of the simply typed λ-calculus. Each dimension of the cube corresponds to a new kind of dependency between terms and types.
