Papers by Michael F. Singer
Preprints
 Consistent systems of
linear differential and difference equations (with R.
Schaefke), Preprint, 2016
 Mahler equations and rationality
(with R.
Schaefke), Preprint, 2016. This contains another proof of
a result of Adamczewski and Bell concerning Mahler equations: A
formal power series satisfying a
p− and a q−Mahler equation over C(x)
with multiplicatively independent positive integers p
and q is a rational function. The proof presented here is
selfcontained and is essentially a compilation of proofs
contained in the preprint "Consistent systems of linear
differential and difference equations",
