Drinfeld modules in the arithmetic of division algebras over function fields, exploiting properties of modular schemes. This paper deals with a class of finite structures known as division algebras. For this purpose, given a finitedimensional central division algebra d over a field k, one defines gen ′ (d) as the collection of classes [d ′ ] ∈ br(k) with the property that a finite field.

On finite division algebras david g. Neither the existence nor the uniqueness of f q is obvious. In mathematics, an algebra over a field (often simply called an algebra) is a vector space equipped with a bilinear product.thus, an algebra is an algebraic structure consisting of a set together with operations of multiplication and addition and scalar multiplication by elements of a field and satisfying the axioms implied by vector space and bilinear.
