Upper bounds for the degrees of decomposable forms of given discriminant
Kálmán Győry · Acta Arithmetica · 1994
1. Introduction. In our paper [5] a sharp upper bound was given for the degree of an arbitrary squarefree binary form F ∈ ℤ[X,Y] in terms of the absolute value of the discriminant of F. Further, all the binary forms were listed for which this bound cannot
