On a result of Fel'dman on linear forms in the values of some E-functions
Keijo Väänänen
We shall consider a result of Fel'dman, where a sharp Baker-type lower bound is obtained for linear forms in the values of some E-functions. Fel'dman's proof is based on an explici…

On simultaneous approximation of the values of certain Mahler functions
Keijo Väänänen, Wen Wu
In this paper, we estimate the simultaneous approximation exponents of the values of certain Mahler functions. For this we construct Hermite-Padé approximations of the functions un…

Algebraic independence of reciprocal sums of certain Fibonacci-type numbers
Peter Bundschuh, Keijo Väänänen
The paper studies algebraic independence of certain reciprocal sums of Fibonacci and Lucas sequences. Also more general binary recurrences are considered. The main tool is Mahler's…
