Assim, o principal objetivo deste trabalho é a construção de reticulados algébricos de dimensão 2; 4; 6 e 8, com densidade de centro ótimo. / In this work, we see that the image of an ideal from the algebraic integer ring of the numbers ¯elds by the Minkowski homomorphism is a lattice, named algebraic lattice. In this way, the main aim of this work is the construction of algebraic lattices of dimensions 2,4,6 and 8, with the center density excellent.
