Homogenization technique

Definition

The homogenization technique is a mathematical method used to analyze and simplify complex geometric structures by transforming them into a more uniform or standardized form. This process helps in studying properties of convex cones, as it allows for the examination of their behavior under scaling and affine transformations, facilitating a deeper understanding of their geometric and functional characteristics.
