Algebraic Points of Any Given Degree on the Affine Equation Curve y11= x4(x − 1)4

The quotients of Fermat curves Cr,s(p) are studied by SALL who extends the work of Gross and Rohlich. Among these studies are the cases Cr,s(11) for r = s = 1. COLY and Sall have explicitly determined the algebraic points of degree at most 3 on for the cases Cr,s(11) for r = s = 2. Our work focuses we determine explicitly the algebraic points of a given degree over on the curve C4,4(11) of affine equation y11= x4(x − 1)4 which is a special case of Fermat quotient curves. Our study concerns the cases Cr,s(11) for r = s = 4. This note completes pevious work of Gassama and Sall who explicitly determined the algebraic points of degree at most three on the even curve. It seems that the finiteness of the Mordell-Weil group of rational points of the Jacobien J4,4(11)() is an essential condition. So to determine the algebraic points on the curve C4,4(11) we need a finiteness of the Mordeill-Weill group of rational points of the Jacobien J4,4(11)(). The Mordell-Weil group J4,4(11)() of rational points of the Jacobien is finite according to Faddev. Our note is in this framework. Our essential tools in this note are the Mordell-Weil group J4,4(11)() of the Jacobien of C4,4(11) the Abel-Jacobi theorem and the study of linear systems on the curve C4,4(11). The result obtained concerns some quotients of Fermat curves. Indeed, the curve of affine equation y11= x4(x − 1)4, we made an extension of the work of work of Gassama and Sall by explicitly determining the algebraic points of given degree on the curve C4,4(11) and this is what makes this note very interesting.
