Two double inequalities for k-gamma and k-Riemann zeta functions
, 2014 By using methods in the theory of majorization, a double inequality for the gamma function is extended to the k-gamma function and the k-Riemann zeta function.MSC:33B15, 26D07, 26B25.

Characterization of the monotone polar of subdifferentials
, 2013 We show that a point is solution of the Minty variational inequality of subdifferential type for a given function if and only if the function is increasing along rays starting from that point.

Continuity properties of K-midconvex and K-midconcave set-valued maps
Mathematical Inequalities & Applications, 2019 A recent result on the continuity of midconvex functionals upper bounded on a not null-finite set (see [2]) is extended to K -midconvex and K -midconcave set-valued maps. Mathematics subject classification (2010): 26B25, 39B62, 54C60.

Characterizations of minimal elements of upper support with applications in minimizing DC functions
Open MathematicsIn this study, we discuss on the problem of minimizing the differences of two non-positive valued increasing, co-radiant and quasi-concave (ICRQC) functions defined on XX (where XX is a real locally convex topological vector space).

Characterizations of bivariate conic, extreme value, and Archimax copulas
Dependence Modeling, 2017 Based on a general construction method by means of bivariate ultramodular copulas we construct, for particular settings, special bivariate conic, extreme value, and Archimax copulas. We also show that the sets of copulas obtained in this way are dense in

Relative Schur-convexity on global NPC spaces
Mathematical Inequalities & Applications, 2015 We introduce the concept of relative convexity on spaces with global nonpositive curvature and illustrate its usefulness by a number of inequalities involving the convex functions on such spaces.

A universal bound on the variations of bounded convex functions [PDF]
, 2015 Given a convex set $C$ in a real vector space $E$ and two points $x,y\in C$, we investivate which are the possible values for the variation $f(y)-f(x)$, where $f:C\longrightarrow [m,M]$ is a bounded convex function. We then rewrite the bounds in terms of

Explicit formulas for $C^{1,1}$ Glaeser-Whitney extensions of 1-fields in Hilbert spaces
, 2018 We give a simple alternative proof for the $C^{1,1}$--convex extension problem which has been introduced and studied by D. Azagra and C. Mudarra [2].
