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 \(x\)' ...

Plot points with coordinates where \(x\) and \(y\) are equal. Three points are sufficient, but more can be plotted. Draw a line through the plotted points. If \(x\) is positive, \(y\) is negative. If ...

Given a homogeneous k-th order differential operator A(D) on ℝn between two finite dimensional spaces, we establish the Hardy inequality ${\int }_{{\mathrm{\mathbb ...
