“…7 Some of the most important mathematical inequalities are obtained by using the idea of convexity. [8][9][10][11][12] Over 100 years ago, Jensen introduced the inequality for convex function which is paramount and extensively used inequality in the literature for application purpose. In the literature of inequalities, Jensen inequality is of pivotal importance because other classical inequalities, eg, Ky-Fan, Hölder, Levinson's, Beckenbach-Dresher, Minkowski's, arithmetic-geometric, and Young's inequalities, can be deduced from this inequality.…”
