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,
Sesquilinear form to is Similarly, is orthogonal to with respect to , written (or simply if can be inferred from the context), when . This relation need not be symmetric, i.e. does not imply (but see "" below). A sesquilinear form is reflexive if, for all , That is, a sesquilinear form is reflexive precisely when the derived orthogonality relation is symmetric. A -sesquilinear form is called -Hermitian if there exists such that, for all , If , the form is called -"Hermitian", and if , it is called -"anti-Hermitian". (When is implied, respectively simply "Hermitian" or "anti-Hermitian".) For a nonzero -Hermitian
