Abstract
In the present thesis we focus on how to solve the equation x+yz=1 completely in unknowns x,y,z chosen from the group G generated by t and 1t in the function field F(t), where F is the field with p elements. The general theory is wellunderstood but there are rather few examples. Here we find at most 243 (so independent of p) families of solutions parametrized by (at most) a pair of primepower exponents; these correspond to two independent actions of Frobenius. We also indicate how to go further by finding all solutions in the radical of G in the algebraic closure of F(t).
