We describe algorithmic tools to compute with exact sequences of Abelian groups. Although simple in nature, these are essential for a number of applications such as the determination of the structure of (Z K /m) \* for an ideal m of a number field K, of ray class groups of number fields, and of cond

β¦ Synopsis
In this note, we present algorithms to deal with finite near-rings, the appropriate algebraic structure to study non-linear functions on finite groups. Just as rings (of matrices) operate on vector spaces, near-rings operate on groups. In our approach, we have developed efficient algorithms for a variety of problems that involve the structure of the operation of a near-ring on a group. From this, we retrieve information about the near-ring itself.

Given the ring of integers R of an algebraic number field K, for which natural Ε½ . number n is there a finite group G ; GL n, R such that RG, the R-span of G, Ε½ . Ε½ .

The study of asymptotic properties of the conjugacy class of a random element of the finite affine group leads one to define a probability measure on the set of all partitions of all positive integers. Four different probabilistic understandings of this measure are given-three using symmetric functi
The Iterative Group Implicit (IGI) algorithm is developed for the parallel solution of general structural dynamic problems. In this method the original structure is partitioned into a number of a subdomains. Each subdomain is solved independently and therefore concurrently, using any traditional dir
Tits has shown that a finitely generated matrix group either contains a nonabelian free group or has a solvable subgroup of finite index. We give a polynomial time algorithm for deciding which of these two conditions holds for a given finitely generated matrix group over an algebraic number field. N
A finitely generated algebra A in a variety V V is called finitely determined in V V if there exists a finite V V-consistent set of equalities and inequalities in an alphabet containing the generating set of A, which, together with the identities of V V , yields all relations and non-relations of A.
