Algebraic Number Theory, a Computational Approach
... a finitely generated free abelian group is finitely generated. Then we see how to represent finitely generated abelian groups as quotients of finite rank free abelian groups, and how to reinterpret such a presentation in terms of matrices over the integers. Next we describe how to use row and column ...

Quadratic Equations
... square on the right side, is half the coefficient of the x term on the left. Also, the constant on the left is the square of the constant on the right. So, to find the constant term of a perfect square trinomial, we need to take the square of half the coefficient of the x term in the trinomial (as l ...

Coins with arbitrary weights, J. Algorithms 25
... are balanced, and it is known that the vector of weights of the coins lies in Wm,k , then the vector of correct weights must lie in ker(A) ∩ Wm,k , showing that the algorithm is correct iff there are no nonconstant vectors in ker(A) ∩ Wm,k . We have thus seen that any matrix A ∈ An,m defines a weigh ...

Splitting of short exact sequences for modules
... In Section 2 we will give two ways to characterize when a short exact sequence of Rmodules splits. Section 3 will discuss a few consequences. Before doing that, we want to stress that being split is not just saying there is an isomorphism M → N ⊕ P of Rmodules, but how the isomorphism works with the ...
