Integer Points on A^4+B^4+2*C^4=4*D^4
[2026.05.01]A^4+B^4+2*C^4=4*D^4の整点
■Diophantine Equation
A^4+B^4+2*n^2*C^4=4*D^4 ----------(1)
を満たす自明でない整数の組(A,B,C,D) (ただし A*B*C*D!=0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=x+y,B/D=x-y.C/D=tとすると、
2*(x^4+6*x^2*y^2+y^4)+2*n^2*t^4=4
x^4+6*x^2*y^2+y^4+n^2*t^4=2 ----------(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に対して、
(u^2+1)*y^2=--(u^2+4*u+5)*x^2-(u^2+2*u-1) ----------(5a)
±n*(u^2+1)*t^2=2*(u^2+2*u-1)*x^2+(u^2-2*u^1) ----------(5b±)
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(u,x)
%1 = ((-u^2 - 4*u - 5)/(u^2 + 1))*x^2 + ((-u^2 - 2*u + 1)/(u^2 + 1))
gp > TT2(n,u,x)
%2 = ((2*u^2 + 4*u - 2)/(n*u^2 + n))*x^2 + ((u^2 - 2*u - 1)/(n*u^2 + n))
gp > x^4+6*x^2*YY2(u,x)+YY2(u,x)^2+n^2*TT2(n,u,x)^2
%5 = 2
■2次曲線(5a),(5b±)は、常にnon-singularである。
2次曲線(5a)の右辺の判別式は
-4*(u^2+4*u+5)*(u^2*2+u-1)
となり、有理数の根を持たないので、任意の有理数uについて、non-singularである。
同様に、2次曲線(5b±)の右辺の判別式は
-4*2*(u^2+2*u-1)*(u^2-2*u-1)
となり、有理数の根を持たないので、任意の有理数uについて、non-singularである。
■以下では、n=1とする。Pari/GPで簡単なプログラムを作成して、小さい整数解を調べると、
1^4+1^4+2*1^4=4*1^4
11^4+43^4+2*19^4=4*31^4
21^4+37^4+2*13^4=4*27^4
121^4+223^4+2*19^4=4*161^4
209^4+471^4+2*717^4=4*617^4
が見つかった。
■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、uの分子が偶数、uの分母が奇数であり、2つの2次曲線(5a)と(5b±)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(重複を含む)422個のuが抽出される。

■これらのuについて、(3),(5a),(5b)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+578*C^4=4*D^4(n=17のとき)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, 0 < Dを満たすように、A,B,C,Dの符号を変更したり、A,B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。
