초록/해제  
요약In this thesis, we prove the existence of a secondary term for the count of cubic extensions of the function field Fq(t) of fixed absolute norm of discriminant. We show that the number of cubic extensions with absolute norm of discriminant equal to q2N is c1q2N − ci 2q5N/3 + Oε (q (3/2+ε)N) , where c1 and ci2 are explicit constants and ci2 only depends on N (mod 3). This builds on the work of Bhargava-Shankar-Tsimerman and Taniguchi-Thorne, who proved the existence of a secondary term for the count of cubic extensions of Q with bounded discriminant. Our approach uses a parametrization of Miranda and Casnati-Ekedahl, which can be seen as a geometric version of the classical parametrization by binary cubic forms used by Davenport-Heilbronn. This allows us to count and sieve for smooth curves embedded in Hirzebruch surfaces, in the same spirit as Zhao and Gunther.
