✦ Synopsis


We give a tradeoff theorem between the area and the aspect ratio required by any planar straight-line drawing of K 2,n on the integer lattice. In particular we show that if the drawing is contained in a rectangle of area O(n) then the rectangle must have aspect ratio (n), and conversely, if the aspect ratio is O(1) then the area must be (n 2 / log 2 n).

Four essentially different interpretations of a lower bound for linear operators are shown to be equivalent for matrices (involving inequalities, convex sets, minimax problems, and quotient spaces). Properties stated by von Neumann in a restricted case are satisfied by the lower bound. Applications
