Schur-convexity and Schur-geometrically concavity of Gini means
The monotonicity and the Schur-convexity with parameters (s, t) in R2 for fixed (x, y) and the Schur-convexity and the Schur-geometrically convexity with variables (x, y) in R++ for fixed (s, t) of Gini mean G(r, s;x, y) are discussed. Some new inequalities are obtained.
متن کاملSome Results on Convexity and Concavity of Multivariate Copulas
This paper provides some results on different types of convexity and concavity in the class of multivariate copulas. We also study their properties and provide several examples to illustrate our results.
متن کاملDetection of convexity and concavity in context.
Sensitivity to shape changes was measured, in particular detection of convexity and concavity changes. The available data are contradictory. The author used a change detection task and simple polygons to systematically manipulate convexity/concavity. Performance was high for detecting a change of sign (a new concave vertex along a convex contour or a new convex vertex along a concave contour). ...
متن کاملPolyhedral aspects of Submodularity, Convexity and Concavity
The seminal work by Edmonds [9] and Lovász [39] shows the strong connection between submodular functions and convex functions. Submodular functions have tight modular lower bounds, and a subdifferential structure [16] in a manner akin to convex functions. They also admit polynomial time algorithms for minimization and satisfy the Fenchel duality theorem [18] and the Discrete Seperation Theorem ...
متن کاملThroughput Concavity and Response Time Convexity
Throughput and response time are two performance measures which are commonly used to judge a system’s performance. As a result, it is important to determine the effect upon throughput and response time as other system parameters are varied. The parameter considered in this paper is the multiprogramming level. Attention is restricted to single-class, closed, product-form networks [2]. Only basic...
