Notes on Extremal Approximately Convex Functions and Estimating the Size of Convex Hulls
This is a set of notes that is basically and expanded version of the paper Extremal Approximately Convex Functions and Estimating the Size of Convex Hulls. The differences are a few extra pictures, Section 2.7 which is an exposition of results of Ng and Nikodem [5] about measurable approximately convex functions, and an alternate proof of Theorem 2.27 is included. Contents 1. Introduction 2 2. ...
متن کاملApproximate Hermite––hadamard Type Inequalities for Approximately Convex Functions
In this paper, approximate lower and upper Hermite–Hadamard type inequalities are obtained for functions that are approximately convex with respect to a given Chebyshev system. Mathematics subject classification (2010): Primary 39B22, 39B12.
متن کاملSome Results on Convex Spectral Functions: I
In this paper, we give a fundamental convexity preserving for spectral functions. Indeed, we investigate infimal convolution, Moreau envelope and proximal average for convex spectral functions, and show that this properties are inherited from the properties of its corresponding convex function. This results have many applications in Applied Mathematics such as semi-definite programmings and eng...
