If the continuous function u satisfies the inequality $\mathrm{u}(\mathrm{x},\mathrm{y})\le \mathrm{f}(\mathrm{x},\mathrm{y})+{\int }_{0}^{\mathrm{x}}{\int }_{0 ...
Inequalities are the relationships between two expressions which are not equal to one another. The symbols used for inequalities are <, >, ≤, ≥. \(7 \textgreater x\) reads as '7 is greater than \(x\)' ...
The operator convex functions of several variables are characterized in terms of a non-commutative generalization of Jensen's inequality, extending previous results of F. Hansen and G.K. Pedersen for ...
