具有次极大对称性的七阶ODE
On the 7th order ODE with submaximal symmetry
摘要:
我们找到了唯一的七阶常微分方程的一般解,该方程允许十维接触对称群。该常微分方程的积分曲线是$\PP^3$中的有理接触曲线,它产生六次有理平面曲线。这些曲线的模空间是齐性空间$Sp(4)/SL(2)$的实形式。
英文摘要:
We find a general solution to the unique 7th order ODE admitting ten dimensional group of contact symmetries. The integral curves of this ODE are rational contact curves in $\PP^3$ which give rise to rational plane curves of degree six. The moduli space of these curves is a real form of the homogeneous space $Sp(4)/SL(2)$.
