Primes in quadratic fields
... any integer into irreducible factors is unique apart from the order of the factors and ambiguities between associated factors, i.e. the irreducible factors in any two factorizations of a given integer can be ordered such that corresponding factors are associates. The distinction between primes and i ...

Algebraic D-groups and differential Galois theory
... For G an algebraic group over the differential field K, an algebraic Dgroup structure on G is precisely an extension of the derivation ∂ on K to a derivation on the structure sheaf of G, respecting the group operation. Algebraic D-groups belong entirely to algebraic geometry, and Buium [3] points out ...

If the triplet (a, b, c) ∈ N3 is compositum-feasible then it is also sum-feasible and product-feasible. Proof ...
