In economic models convexity plays an important role in establishing the existence of solutions. Therefore it is of importance to develop techniques for accommodating nonconvexity. In this paper the authors consider cooperative games with side payments.

When a mapping is univalent (one-to-one) on a set is a question which has received considerable study. Much of the recent research has focused on the shape of the set on which the mapping is defined. It has been suggested, in fact, that the set must be convex for univalence to hold. This paper presents conditions under which the set need not be convex.

Nonconvexities in Stochastic Control Models
International Economic Review, 1995Summary: Nonconvexities in the criterion function of adaptive control problems were first found about ten years ago with numerical methods. Recently they have been confirmed by Mizrach with analytical methods. He found that a source of the nonconvexity was the probing component of the cost- to-go.

An Algorithm for Separable Nonconvex Programming Problems II: Nonconvex Constraints
Management Science, 1971We extend a previous algorithm in order to solve mathematical programming problems of the form: Find x = (x1, …, xn) to minimize ∑φi0(xi) subject to x ∈ G, l ≦ x ≦ L and ∑φij(xi) ≦ 0, j = 1, …, m. Each φij is assumed to be lower semicontinuous, possibly nonconvex, and G is assumed to be closed.

Nonconvex Online Support Vector Machines
IEEE Transactions on Pattern Analysis and Machine Intelligence, 2011In this paper, we propose a nonconvex online Support Vector Machine (SVM) algorithm (LASVM-NC) based on the Ramp Loss, which has the strong ability of suppressing the influence of outliers. Then, again in the online learning setting, we propose an outlier filtering mechanism (LASVM-I) based on approximating nonconvex behavior in convex optimization ...

Nonconvex Duality in Optimal Control
SIAM Journal on Control and Optimization, 2005The authors consider the optimal control problem of minimizing \(\ell(T,x(T))\) over all solutions \(x(t)\) of a differential inclusion and all end times \(T\geq 0\). The main result in the paper states that the optimal value function of the problem is the supremum \(\sup_\psi \psi(0,x(0))\) over all locally Lipschitz functions \(\psi\) satisfying the ...

Nonconvex Variational Inequalities
2015In this chapter, we consider a nonconvex variational inequality defined on proximally smooth set and star-shaped set. Based on arguments of the fixed point theorem and the proximal normal method, some existence and uniqueness results concerning the nonconvex variational inequality are proved under suitable conditions.
