context_page_description: In mathematics, the Peano surface is the graph of the two-variable function
  It was proposed by Giuseppe Peano in 1899 as a counterexample to a conjectured criterion for the existence of maxima and minima of functions of two variables.
  The surface was named the Peano surface by Georg Scheffers in his 1920 book Lehrbuch der darstellenden Geometrie. It has also been called the Peano saddle.
