A Note on Transcendental Power Series Mapping the Set of Rational Numbers into Itself
In this note, we prove that there is no transcendental entire function such that and , for all sufficiently large , where .
In this note, we prove that there is no transcendental entire function such that and , for all sufficiently large , where .
We prove a result on approximations to a real number θ by algebraic numbers of degree ≤ 2 in the case when we have certain information about the uniform Diophantine exponent ω̂ for the linear form x₀ + θx₁ + θ²x₂.
A modification of a classical number-theorem on Diophantine approximations is used for generalizing H. kielhöfer's result on bifurcations of nontrivial periodic solutions to nonlinear wave equations.
