Stable polynomials, Lorentzian polynomials and discrete convexity [PDF]
, 2019 A multivariate polynomial is stable if it is nonzero whenever all its variables have positive imaginary parts. Lorentzian polynomials generalize homogeneous and stable polynomials.

A note on fuzzy convexity [PDF]
, 2004 In this paper, we introduce and study the concept of semistrictly convex fuzzy sets.We also prove that for the upper semicontinuous case, the class of semistrictly convex fuzzy sets lies between the convex and strictly convex classes.

Hidden Convexity in Partially Separable Optimization [PDF]
The paper identifies classes of nonconvex optimization problems whose convex relaxations have optimal solutions which at the same time are global optimal solutions of the original nonconvex problems. Such a hidden convexity property was so far limited to

Characterizing Convexity of Games using Marginal Vectors [PDF]
In this paper we study the relation between convexity of TU games and marginal vectors.We show that if specfic marginal vectors are core elements, then the game is convex.We characterize sets of marginal vectors satisfying this property, and we derive ...
