Discriminante da potÃncia de um nÃmero algÃbrico / On the discriminant of the power of an algebraic number

Joserlan Perote da Silva 28 July 2010 (has links)
FundaÃÃo de Amparo à Pesquisa do Estado do Cearà / Conselho Nacional de Desenvolvimento CientÃfico e TecnolÃgico / Seja alfa um nÃmero algÃbrico que nÃo à raiz de um nÃmero racional. Mostraremos que o discriminante de alfa elevado a n tende a infinito com n tendendo a infinito e daremos um limite inferior para este discriminante em termos do grau de alfa, sua medida de Mahler e n. / Let alfa be an algebraic number which is not a root of a racional number. We show that the discriminant of alfa n tends to infinity with n tending to infinity and give a lower bound for this discriminant in terms of the degree of alfa, its Mahlerâs measure and n.
