N2 - We prove that every matrix in SL 2(ℤ[1/p]) can be written as a product of at most five elementary matrices. This statement can also be interpreted in terms of short division chains in ℤ[1/p]. Similar bounds for the number of factors were known previously only under the generalized Riemann hypothesis. © 2013. Published by Oxford University Press.
