Fermat's Last Theorem, Solution Sets v6
摘要:
导出了C^n = A^n + B^n的非零整数解集。n = 2的非零整数解集是[C -(a + b)]^2 = 2ab。变量a和b分别等于(C-A)和(C-B),并且是2M^2的非零整数因子,其中M是非零整数。C大于(a + b),因为当C小于(a + b)时,2ab的平方根是虚数。C等于或大于(a + b + 1),因为我们只考虑整数。n = 2的解集的推导适用于n = 3,n = 4,并推广到n。n = n的解集为[C -(a + b)]^n = ab([n:2]C^(n-2)*(2)- [n:3]C^(n-3)*(3a + 3b)+. + [n:n] {[n:1]a^(n-2)+ [n:2]a^(n-3)*b^1 + [n:3]a^(n-4)*b^2 +. + [n:n-1]b^(n-2)})。其中,二项式系数[n:r] = n!/ [(n- r)!r!]是二项式幂(1 + x)^n的多项式展开式中x^r项的系数,如果r > n,则[n:r] = 0。将该方程除以[C-(a + b)]^(n-2),得到[C-(a + b)]^2。[C -(a + b)]^2的解集等于2ab。只有当n等于2时,第n个解集才等于2ab。[C -(a + b)]^2(即,当n大于2时,[C-(a + b)]^n除以[C -(a + b)]^(n-2))总是大于2ab。非零整数解只存在于n = 2时。
英文摘要:
The non-zero integer solution set is derived for C^n = A^n + B^n. The non-zero integer solution set for n = 2 is [C - (a + b)]^2 = 2ab. The variables a and b equal (C - A) and (C - B) respectively and are nonzero integer factors of 2M^2 where M is a non-zero integer. C is greater than (a + b) since the square root of 2ab is an imaginary number when C is less than (a + b). C is equal or greater than (a + b + 1) since we are only considering whole numbers. The derivation of the solution set for n = 2 is applied to n = 3, n = 4, and generalized to n. The solution set for n = n is [C - (a + b)]^n = ab([n:2]C^(n-2)*(2) - [n:3]C^(n-3)*(3a + 3b)+ ... + [n:n] {[n:1]a^(n-2) + [n:2]a^(n-3)*b^1 + [n:3]a^(n-4)*b^2 +... + [n:n-1]b^(n-2)}). Where the binomial coefficient [n:r] = n!/[(n - r)!r!] is the coefficient of the x^r term in the polynomial expansion of the binomial power (1 + x)^n and [n:r] = 0 if r > n. Divide this equation by [C-(a + b)]^(n-2) to obtain [C-(a + b)]^2. The solution set for [C - (a + b)]^2 equals 2ab. The nth solution set equals 2ab only when n equals 2. [C - (a + b)]^2 (I.e., [C - (a + b)]^n divided by [C - (a + b)]^(n-2)) is always greater than 2ab when n is greater than 2. Non-zero integer solutions exist only for n = 2.
