Cuneiform is a system of writing first developed by the ancient Sumerians of Mesopotamia c. 3500-3000 BCE. It is considered the most significant among the many cultural contributions of the Sumerians and the greatest among those of the Sumerian city of Uruk which advanced the writing of cuneiform c. 3200 BCE.
In the mathematical theory of singularities a cusp is a type of singular point of a curve. Cusps are local singularities in that they are not formed by self intersection points of the curve.The plane curve cusps are all diffeomorphic to one of the following forms: x 2 â y = 0, where k â¥ 1 is an integer. An ordinary cusp is given by x 2 â y 3 = 0, i.e. the zero-level-set of a type A 2 -singularity. 2  Let f (x, y) be a smooth function of x and y and assume, for simplicity, that f (0,0) = 0. 3  Then a type A 2 -singularity of f at (0,0) can be characterised by:
