The cheese originally comes from Southern Ostrobothnia, Northern Finland, and Kainuu. The milk is curdled and set to form a round disk from two to three centimeters thick. After this, leipäjuusto is baked, grilled,
Bilinear form form on a normed vector space is elliptic, or coercive, if there is a constant such that for all , Given a ring "R" and a right "R"-module "M" and its dual module "M", a mapping is called a bilinear form if for all , , . The mapping is known as the "natural pairing", also called the "canonical bilinear form" on . A linear map induces the bilinear form , and a linear map induces the bilinear form . Conversely, a bilinear form induces the "R"-linear maps and . Here, "M" denotes the double dual of "M". Bilinear form
