摘要:
Let p be a prime ,and r≥0 be a integer .Using the deeply result of generalized Fermat equation ,we prove that if 3≤ q<100 and q≠31 ,then the superelliptic curve yp = x(x+ qr ) has only ordinary rational point y=0 when p≥5 .If q=5 ,11 ,23 ,29 ,41 ,47 ,59 ,83 ,we give all of the rational points (x ,y) in the superelliptic curve .Further-more ,if q=3 and r=1 ,the superelliptic curve yp = x(x+3) has a non-trivial rational point (x ,y) only when p=2 .%设p为素数,r≥0是整数.利用广义Fermat方程的深刻结论证明了:若3≤q<100,q≠31,则当p≥5时,超椭圆曲线yp=x(x+qr)上仅有平凡的有理点y=0;当q=5,11,23,29,41,47,59,83时,给出了该超椭圆曲线所有的有理点(x,y).特别地,当q=3且r=1时,证明了超椭圆曲线yp=x(x+3)仅在p=2时有非平凡的有理点(x,y),并给出了此时所有的非平凡有理点.
