Types of level curves-In a previous work of the authors, a result to algorithmically compute the topology types of the level curves of an algebraic surface, is given From this result, here we derive applications basedType of the level curve of S at z = z0, for every z0 2 R, ie the topology types of the algebraic plane curves F(x;y;z0) with z0 2 R We observe that the two conditions that we have imposed above to the polynomial F(x;y;z) can be assumed wlog Indeed, if F has any factor only depending on z then one can write F(x;y;z) = H(z) ¢ G(x;y;z) Thus, the surface S decomposes as the union

Once this has been done, the different topology types of the level curves of the surface can be computed by means of wellknown algorithms In this paper, we address the problem of determining the zvalues where the topology type of the level curves of an algebraic surface may change In the case when the surface is bounded and nonsingular, this question is solved by These types of curves are low and flat at Level 1, rise sharply at Level 2, and flatten off at Levels 3 and 4 Trends that follow this type of curve include female literacy, vaccination rates, and refrigeration This is because once people reach Level 2 they can afford these luxuries and start consuming them en masse But the increase slows down in Levels 3 and 4 becauseThere must be some underlying mathematical theory!
