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