  Abstract:
In this paper, we study the complexity of performing some linear algebra operations such as Gaussian elimination and minimal polynomial computation over an algebraic extension field. For this, we use the theory of Gröbner bases to employ linear algebra methods as well as to work in an algebraic extension. We show that this has good complexity. Finally, we report an implementation of our algorithms in WOLFRAM MATHEMATICA and illustrate its effectiveness via several examples.
