Hello Günther

Provided you consider relations part of mathematics ('The Haskell
Road' book certainly does as does, as does John O'Donnell et als.
'Discrete Mathematics Using a Computer'), then you might consider
fundeps as much 'derived' from maths as engineered. See the paper from
the 2008 Haskell Symposium.
