Simmetrik ko`phadlar

Endi f(x1,...,xn)- m darajali simmetrik ko`phad bo`lsin. xn = 0 deb olamiz, induktiv farazimizga ko`ra

• Endi f(x1,...,xn)- m darajali simmetrik ko`phad bo`lsin. xn = 0 deb olamiz, induktiv farazimizga ko`ra
• f(x1,x2,...,xn-1,0) = g1((s1)0,....,(sn-1)0),
• bunda g1-biror A[y1,...,yn-1] dagi o`lchovi esa  m ( f ning darazasi
• xn = 0 qo`yish natijasida pasayishi mumkin) bo`lgan ko`phad, (s1)0,....,(sn-1)0 - esa x1,...,xn-1 larning elementar simmetrik ko`phadi. Bunda ravshanki, deg g1(s1,...,sn-1)  m. Ushbu
• f1(x1,...,xn)= f(x1,...,xn)-g1(s1,...,sn-1) (1)
• ko`phadning x1,...,xn bo`yicha to`la darajasi m dan katta emas va
