Description
Angelos Koutsianas has written code to solve general 3term Sunit equations over Q, i.e. to find all solutions to x+y=1 where x,y are rationals supported on the primes in a given finite set S. This is based on de Weger's thesis.
The code is currently being tested, and will be made into a new branch here.

The above commit (f97b22f) includes 7.1.beta1, and the new file passes its tests.

I think we need to added the new file S_unit_equation.py to the reference manual, and I will try to do that. Also, the file aith.py was moved and I am not sure that the reference manual has been adjusted correctly.

comment:7 Changed 4 years ago by
Docs now build without errors, I will work on the text a bit.

d0fb02b  fix some docstring formatting in Sunit eqn code

comment:9 Changed 4 years ago by
The docstrings now look OK, though perhaps not all functions are explained adequately (and the specific reference should be checked as I was not sure which were to Smart and which to de Weger). I am finished with this code for now.
