👉 In mathematics, a "vergence" is a concept related to vector spaces. A vector space is an algebraic structure that allows addition and scalar multiplication of vectors in such a way that the result is also a vector. This means that for any two vectors \(u\) and \(v\), there exists a unique vector \(w\) such that \(w + v = u\) and \(w \cdot v = 0\). A vergence (also called a linear span) in a
