Convex optimization — Convex minimization, a subfield of optimization, studies the problem of minimizing convex functions over convex sets. Given a real vector space X together with a convex, real valued function defined on a convex subset of X, the problem is to find … Wikipedia
Convex preferences — In economics, convex preferences refer to a property of an individual s ordering of various outcomes which roughly corresponds to the idea that averages are better than the extremes . The concept roughly corresponds to the law of diminishing… … Wikipedia
Quasi-analytic function — In mathematics, a quasi analytic class of functions is a generalization of the class of real analytic functions based upon the following fact. If f is an analytic function on an interval , and at some point f and all of its derivatives are zero,… … Wikipedia
Quasi-polynomial — In mathematics, a quasi polynomial (pseudo polynomial) is a generalization of polynomials. While the coefficients of a polynomial come from a ring, the coefficients of quasi polynomials are instead periodic functions with integral period. Quasi… … Wikipedia
Orthant-wise limited-memory quasi-Newton — (OWL QN) is a numerical optimization algorithm that belongs to the class of quasi Newton methods, and is specifically designed to serve in the training/fitting algorithm of log linear (MaxEnt) models with regularization. It minimizes functions of … Wikipedia
Sion's minimax theorem — In mathematics, and in particular game theory, Sion s minimax theorem is a generalization of John Von Neumann s minimax theorem.It states:Let X be a compact convex subset of a linear topological space and Y a convex subset of a linear topological … Wikipedia
Indirect utility function — In economics, a consumer s indirect utility functionv(p, w) gives the consumer s maximal utility when faced with a price level p and an amount of income w. It represents the consumer s preferences over market conditions.This function is called… … Wikipedia
Nekhoroshev estimates — The Nekhoroshev estimates are an important result in the theory of Hamiltonian systems concerning the long time stability of solutions of integrable systems under a small perturbation of the Hamiltonian. The first paper on the subject was written … Wikipedia
Fundamental theorems of welfare economics — There are two fundamental theorems of welfare economics. The first states that any competitive equilibrium or Walrasian equilibrium leads to an efficient allocation of resources. The second states the converse, that any efficient allocation can… … Wikipedia
