数论 2018-01-22 v1

摘要

Somos-5序列由a0=a1=a2=a3=a4=1a_{0} = a_{1} = a_{2} = a_{3} = a_{4} = 1以及对于m5m \geq 5am=am1am4+am2am3am5a_{m} = \frac{a_{m-1} a_{m-4} + a_{m-2} a_{m-3}}{a_{m-5}}定义。我们将Somos-5序列的算术与椭圆曲线E:y2+xy=x3+x22xE : y^{2} + xy = x^{3} + x^{2} - 2x联系起来,并利用附属于EE的Galois表示的性质,证明了整除Somos-5序列中某项的素数pp的密度等于508710752\frac{5087}{10752}
