👉 The term "bilianic" is a Greek word that refers to a type of mathematical function. In mathematics, a bilinear form is a mapping from two vectors in a vector space into a scalar (a real number) called the weight. A bilinear form can be used to define a norm on the vector space. For example, consider the inner product $\langle \cdot,\cdot \rangle$ on the vector space of all polynomials $P(x)$ over a field $F$,
