On the Normal Closure for a Class of Quartic Algebraic Integer
Zeng Li-jiang · Journal of Henan Normal University · 2008
The paper uses the tools about algebraic number theory to find a class of quartic algebraic integer ±p~(1/2)±q~(1/2),then,it is determined and proved that their minimal polynomial is [x2-(p+q)]2-4pq,and in their normal closure,there are four real inserts and no complex inserts.
