The ∻ (homothetic) symbol is a mathematical operator featuring a wavy tilde positioned between two dots. In geometry, it represents a homothetic transformation—a scaling relationship where an object is enlarged or shrunk from a fixed center point without altering its fundamental shape. While rarely used in everyday text, it is an essential character in advanced mathematical proofs, physics equations, and technical typesetting.
