چکیده

In the article, we present new bounds for the function [Formula: see text] on the interval [Formula: see text] and find sharp estimations for the Sine integral and the Catalan constant based on a new monotonicity criterion for the quotient of power series, which refine the Redheffer and Becker-Stark type inequalities for tangent function.

A Sharp Double Inequality for the Inverse Tangent Function

The inverse tangent function can be bounded by different inequalities, for example by Shafer’s inequality. In this publication, we propose a new sharp double inequality, consisting of a lower and an upper bound, for the inverse tangent function. In particular, we sharpen Shafer’s inequality and calculate the best corresponding constants. The maximum relative errors of the obtained bounds are ap...

Second-order lower radial tangent derivatives and applications to set-valued optimization

We introduce the concepts of second-order radial composed tangent derivative, second-order radial tangent derivative, second-order lower radial composed tangent derivative, and second-order lower radial tangent derivative for set-valued maps by means of a radial tangent cone, second-order radial tangent set, lower radial tangent cone, and second-order lower radial tangent set, respectively. Som...

New Characterizations of Weak Sharp and Strict Local Minimizers in Nonlinear Programming

We consider the problem of identifying weak sharp local minimizers of order m, an important class of possibly non-isolated local minimizers. A characterization of such minimizers is obtained for a nonlinear programming problem with an abstract set constraint. The results are formulated in terms of certain normal and tangent cones to given sets, and generalized directional derivatives of the obj...
