Title in Portuguese
Caracterização de curvas maximais a partir de mergulhos em variedades hermitianas
Keywords in Portuguese
Corpos finitos
Curvas maximais
Variedades hermitianas
Abstract in Portuguese
Uma curva algébrica projetiva, geometricamente irredutível e não singular definida sobre Fq2 de gênero g será Fq2-maximal se seu número de pontos Fq2-racionais for 1+q2+2gq, isto é, a cota superior de Hasse-Weil. Este trabalho detalha a prova do Teorema do Mergulho Natural e a de sua recíproca, desenvolvidas por Gábor Korchmáros e Fernando Torres. Juntos, os dois resultados dão uma caracterização geométrica à propriedade definida aritmeticamente

Characterization of maximal curves from embeddings in Hermitian varieties

Maximal curves
Abstract in English
A projective, geometrically irreducible and non-singular algebraic curve defined over Fq2 of genus g is Fq 2-maximal if its number of Fq2-rational points is 1+q2+2gq, i.e., the Hasse-Weil upper bound. This work details the proof of both Natural Embedding Theorem and its converse, developed by Gábor Korchmáros and Fernando Torres. Together, the two results provide a geometric characterization to the arithmetically defined property.
