  1. For the regular curves, we find two killing fields for the purpose of integrating the structural equations of the p - elastic curves and express the p - elastica by quadratures in a system of cylindrical coordinates. for the star - like affine curves, we solve the euler - lagrange equation by quadratures and reduced the higher order structure equation to a first order linear system by using killing field and the classification of linear lie algebra sl ( 2, r ), sl ( 3, r ) and sl ( 4, r ). we solve the centroaffine p - elastica completely by quadratures

    對于正則曲線的情形,我們發現了兩個用於求解p -彈曲線的結構方程的killing向量場並用積分將p -彈曲線在一個柱面坐標系中表出來,而對仿射星形曲線的情形,我們用積分方法解出了-格朗日方程,利用killing向量場及線李代s1 ( 2 , r ) 、 s1 ( 3 , r )和s1 ( 4 , r )的分類將高階結構方程降為一階線方程,因此我們用積分完全解出了中心仿射p -彈曲線。
