The current quantity encompasses a collection of refereed papers from the MEGA-94 symposium held in Santander, Spain, in April 1994. They hide fresh advancements within the thought and perform of computation in algebraic geometry and current new functions in technology and engineering, rather desktop imaginative and prescient and idea of robotics. the amount can be of curiosity to researchers operating within the parts of laptop algebra and symbolic computation in addition to to mathematicians and desktop scientists drawn to having access to those issues.

Anai, M. Noro, K. Yokoyama 1 Introduction This study is a continuation of Yokoyama et al. [22], which improved the method by Landau and Miller [11] for the determination of solvability of a polynomial over the integers. In both methods, the solvability of a polynomial is reduced, in polynomial time, to that of polynomials, each of which is constructed so that its Galois group acts primitively on its roots. Then, by virtue of P6Jfy's bound [14], solvability of polynomials with primitive Galois groups can be determined in polynomial time.

Here, we need the factorization ofm(x). Since K f is a Galois extension, m(x) is factorized into linear factors over K f and so each root f3i is expressed by a polynomial Bi(Z) in z over Q. Then, each element of G f is determined uniquely by the action on Z = B 1, that is, G f = {g1, . , gN }, where Z9i = Bii = Bi (z). The permutation representation of gk on n f is determined by the following: j = i9k if and only if Ai(Bk(Z)) == Aj(z) in Q[z]1 < m(z) >. To complete the permutation representation of gk, where Z9k = Bk(Z), we have to compute the normal forms Ai(Bk(Z)) for all i, i = 1, ...
