Leipäjuusto Leipäjuusto Leipäjuusto (bread cheese) or juustoleipä, which is also known in the United States as Finnish squeaky cheese, is a fresh cheese traditionally made from cow's beestings, rich milk from a cow that has recently calved. Reindeer or even goat milk can also be used. Commercially available versions are typically made from cow's milk, and they lack some of the colour and flavour because of this. 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,
Quadratic form is also called a quadratic form. Two "n"-dimensional quadratic spaces and are isometric if there exists an invertible linear transformation (isometry) such that The isometry classes of "n"-dimensional quadratic spaces over "K" correspond to the equivalence classes of "n"-ary quadratic forms over "K". Let "R" be a commutative ring, "M" be an "R"-module and be an "R"-bilinear form. A mapping is the "associated quadratic form" of "b", and is the "polar form" of "Q". Alternatively, a quadratic form may be characterized as follows: Two elements "v" and "w" of "V" are called orthogonal if . The kernel of a bilinear
