关于丢番图方程x~4-4x~2y~2+y~4=193
On Diophantine Equation x~4- 4x~2y~2 +y~4 =193
【摘要】 证明了丢番图方程x4-4x2y2+y4=193仅有正整数解(x, y=(1,4)和(4,1),进而又推得丢番图方程 x4- 10x2y2+y4=-1544仅有正整数解(x,y )=( 3, 5)和(5, 3).
【Abstract】 In the paper, the following theorem is proved. Theorem The diophantine equation x4- 4x2y2+y4=193 has only positive integer solutions (x, y)= (l, 4) and (4, l).
