    1212 Algorithms for finding the zero-set of a zero-dim. ideal in Q(a)[x_1,..,x_n],
    13  Roots and Factorization of univariate polynomials over Q(a)[t]
    14  where a is an algebraic number. Written in the frame of the
     13 roots and factorization of univariate polynomials over Q(a)[t]
     14 where a is an algebraic number. Written in the scope of the
    1515 diploma thesis (advisor: Prof. Gert-Martin Greuel) 'Computations of moduli
    1616 spaces of semiquasihomogeneous singularities and an implementation in Singular'.
