👉 Kochliarion is a mathematical concept in algebraic topology. It was introduced by Ivan Ivanovich Kochilin in 1982, and it represents a topological space that can be constructed as the quotient of two spaces. In this construction, we first construct two topological spaces: one is the circle (with its usual topology) and another is the plane (which has only one point). Then, we take the quotient space between these two spaces. The resulting space is
