I am investigating solutions to Fermat's equation $$x^n + y^n = z^n$$ with $x,y,z$ in the Gaussian integers, excluding integers and pure imaginaries.

I have found out that there are only trivial solutions for the $n=3$ and $n=4$ cases, e.g. here.

I would be grateful if you let me know of the current status or if it is already a theorem.

Please don't make posts where "the title says it all". The title is like the writing on the spine of a book; the contents of the post should be sufficient by themsleves. –  Arturo Magidin Mar 11 '12 at 22:10
    
Maybe this should be moved to mathoverflow? –  Ben Crowell Mar 11 '12 at 22:18

@Ben, now I am feeling the same. But Motizens feel that questions posted here should at least have a 24 hour life or more before they pass to the other elite society. –  Herband Mar 11 '12 at 22:56
