## Weierstrass semigroup and Automorphism group of the curves $X_{n,r}$

### Universidade Federal de Uberlandia, Brasil   -   guilhermect@ufu.br

In this talk, we determine the Weierstrass semigroup $H(P_{\infty})$ and the full automorphism group of a certain family of curves, denoted by $X_{n,r}$, which was recently introduced by H. Borges and R. Conceição.

Joint work with Herivelto Borges (Universidade de Sao Paulo) and Alonso Sepúlveda (Universidade Federal de Uberlandia).
