83Semi-differentiability — In calculus, a branch of mathematics, the notions of one sided differentiability and semi differentiability of a real valued function f of a real variable are weaker than differentiability. Contents 1 One dimensional case 1.1 Definitions 1.2… …
84Characterization (mathematics) — In mathematics, the statement that Property P characterizes object X means, not simply that X has property P, but that X is the only thing that has property P. It is also common to find statements such as Property Q characterises Y up to… …
85Network congestion — In data networking and queueing theory, network congestion occurs when a link or node is carrying so much data that its quality of service deteriorates. Typical effects include queueing delay, packet loss or the blocking of new connections. A… …
86Rao–Blackwell theorem — In statistics, the Rao–Blackwell theorem is a result which characterizes the transformation of an arbitrarily crude estimator into an estimator that is optimal by the mean squared error criterion or any of a variety of similar criteria. The Rao… …

89Kachurovskii's theorem — In mathematics, Kachurovskii s theorem is a theorem relating the convexity of a function on a Banach space to the monotonicity of its Fréchet derivative.tatement of the theoremLet K be a convex subset of a Banach space V and let f : K rarr; R… …
90Birnbaum–Orlicz space — In the mathematical analysis, and especially in real and harmonic analysis, a Birnbaum–Orlicz space is a type of function space which generalizes the Lp spaces. Like the Lp spaces, they are Banach spaces. The spaces are named for Władysław Orlicz …
