👉 In mathematics, the term "weierstrassian" is often used to describe a specific type of function that arises in the study of linear transformations. This type of function is named after its creator, Karl Weierstrass, who was born in 1825 and died in 1907. The concept of a linear transformation on a vector space can be described using the following set-up: Let $V$ be a finite-dimensional vector space over a field $\math
