This field investigates the relationships and bounds between various function norms, particularly through inequalities that characterise the smoothness and approximability of functions, as well as the ...

Show values that satisfy an inequality on a set of axes by drawing the line of the corresponding equation and shading the area specified in a question. Include a dashed line for inequalities where the ...
