Integer Points on A^4+12*B^4=C^4+12*D^4
[2026.05.27]A^4+12*B^4=C^4+12*D^4の整点
■Diophantine Equation
A^4+n*B^4=C^4+n*D^4 ----------(1)
を満たす自明でない整数の組(A,B,C,D) (ただし 0 < A < C, 0 < D < Bかつgcd(A,B,C,D)=1)を探す。
以下では、Elkiesの論文(参考文献[1])の方法によって、(1)を満たす整数の組(A,B,C,D)を探す。
■(1)およびD!=0より、A/D=y,B/D=x.C/D=tとすると、
y^4+n*x^4 = t^4+n ----------(2)
y^4-t^4= y n(1-x^4)
(y^2+t^2)*(x^2-t^2) = n*(1+x^2)*(1-x^2)
つまり、(2)を満たす有理数の組(x,y,t)を見つければ良い。
ここで、ある有理数u > 0に対して、
y^2+t^2 = (n/u)*(1+x^2) ----------(2a)
y^2-t^2 = u*(1-x^2) ----------(2b)
よって、
2*u*y^2 = (n+u^2)*x^2+(n-u^2) ----------(3a)
2*u*t^2 = (n-u^2)*x^2+(n+u^2) ----------(3b)
を満たす有理数の組(x,y,t)が存在すれば、(x,y,t)が(2)を満たすことが分かる。

gp > YY2(n,u,x)
%1 = (1/(2*u)*n - 1/2*u)*x^2 + (1/(2*u)*n + 1/2*u)
gp > TT2(n,u,x)
%2 = (1/(2*u)*n + 1/2*u)*x^2 + (1/(2*u)*n - 1/2*u)

■2次曲線(3a),(3b)は、n=u^2のときはsoncularであり、それ以外のときはnon-singularである。
2次曲線(3a)の右辺の判別式は
-4*(n+u^2)*(n-u^2)
となる。ここで、nが平方数でなければ、任意の有理数uについて、判別式は0にならないので、2次曲線(3a)は常にnon-singularである。
nが平方数であるならば、n=u^2のときに限り、2次曲線(3a)はsingularであり。それ以外のuにつては、non-singularである。
同様に、2次曲線(3b)の右辺の判別式は
-4*(n-u^2)*(n+u^2)
となる。nが平方数でなければ、任意の有理数uについて、判別式は0にならないので、2次曲線(3b)は常にnon-singularである。
nが平方数であるならば、n=u^2のときに限り、2次曲線(3b)はsingularであり。それ以外のuにつては、non-singularである。
■以下では、n=12とする。
■有理数uの高さが小さいものから、順に調べる。
例えば、有理数uの高さが100以下の範囲で、2つの2次曲線(3a)と(3b)が共に有理点を持つようなuを選択すると、
以下のように662個のuが抽出される。

■これらのuについて、(2),(3a),(3b)を満たす有理数解(x,y,t)を持たないものもあれば、有理数解(x,y,t)を持つものもある。
これらのuを順に調べれば良い。
ここからは、A^4+B^4=C^4+D^4と同様なので、最終的に得られた整点のみ記述する。
ここで、対応する整点が見つかった各有理数uについて、0 < A < B, 0 < C < D, 0 < A < Cを満たすように、
A,B,C,Dの符号を変更したり、A,B,C,Dを交換して、Dの小さい順に並び替えると、以下のようになる。
