多元多项式的无平方值

Squarefree values of multivariable polynomials

Bjorn Poonen

摘要:

给定Z[x_1,...,x_n],我们计算x在Z^n中的密度,使得f(x)是无平方的,假设abc猜想。给定Z[x_1,...,x_n],我们无条件地计算x在Z^n中的密度,使得gcd(f(x),g(x))=1。无条件地证明了这两个结果的函数域类似物。最后,假设abc猜想,给定f在Z[x]中,我们估计f({1,2,. n})在(Q^*/Q^*2)联合{0}中。

英文摘要:

Given f in Z[x_1,...,x_n], we compute the density of x in Z^n such that f(x) is squarefree, assuming the abc conjecture. Given f,g in Z[x_1,...,x_n], we compute unconditionally the density of x in Z^n such that gcd(f(x),g(x))=1. Function field analogues of both results are proved unconditionally. Finally, assuming the abc conjecture, given f in Z[x], we estimate the size of the image of f({1,2,...,n}) in (Q^*/Q^*2) union {0}.
