Abstract |
|
In this paper, we consider some pure cubic fields of the form K = Q((D3 ± d)1∕3) where D,d ∈ N∗ and d∣3D2. Under certain conditions, we obtain the fundamental unit η of K by ruling out the case where η is the square of a unit. We also give three new classes of vectors, whose Jacobi-Perron Algorithms are periodic. The first ten vectors of a generalized Jacobi-Perron Algorithm are then written down. A generalization of the Bernstein formula is also achieved. |
