F (x, y)= h,(1.1) where F is a form of degree r 5= 3 with integral coefficients, and irreducible over the rationals, has only finitely many solutions. Much later Baker [1] gave explicit, but rather large, bounds for the size of the solutions. Bounds for the number of solutions had been given earlier (see eg Lewis and Mahler [7]), but Evertse [5] was the first to estimate the number of solutions in terms of r and h only. Much better such bounds were recently given by Bombieri and Schmidt [4]. Here we shall deal with the special case of a binary form F= axr-byr. The general estimates can be greatly reduced for forms of this type, giving some evidence to Siegel's conjecture that the number of solutions may be bounded in terms of h and the number of monomials in F. More precisely, our results will be on solutions not only of axr-byr= h, but rather of the diophantine inequality\axr-byr\=£ h with gcd {x, v)= 1.(1.2)
