若Picard数为2的射影K3曲面的自同构是无限级的,则该自同构对应于Pell方程的一个解.本文通过求解这个方程,确定了Picard数为2的射影K3曲面的所有辛和反辛自同构的Salem多项式。
If an automorphism of a projective K3 surface with Picard number 2 is of infinite order, then the automorphism corresponds to a solution of Pell equation. In this paper, by solving this equation, we determine all Salem polynomials of symplectic and anti-symplectic automorphisms of projective K3 surfaces with Picard number 2.
