Definition: Obelizes are a type of mathematical concept in algebraic geometry, particularly in the context of the theory of curves. They were introduced by the French mathematician Édouard Lucas in 1957. An "obellus" is defined as a plane curve (a surface) that satisfies certain conditions. These conditions include the existence of an obelus if it has one or more points where two distinct lines intersect, and they are closed under certain operations such as translation and
closed bracket.
