Unit Equations in Diophantine Number Theory
Jan-Hendrik Evertse
In the number field case when in (9.2) K is a number field and A is a ring of S- integers in K, Györy (1993a) gave a criterion for (9.2) to have only finitely many A *-cosets of solutions. Also in the number field case when T is a group of S-units in K, ...
