一类Hurwitz数的非齐次丢番图逼近

Inhomogeneous Diophantine approximation of some Hurwitzian numbers

Richard T. Bumby, Mary E. Flahive

摘要:

我们继续Takao Komatsu的工作,考虑Hurwitzian数θ的非齐次逼近常数L(θ,n),并在Q(θ)+Q中合理地关联n(r θ+m)/n.目前的工作使用的紧性定理,这种非齐次常数的齐次逼近常数。新的成果包括:对L(θ,ε)为零的这种对θ,ε的特征;对n^2 L(e^{2/s},ε)的小值的考虑;以及小松猜想的证明。

英文摘要:

We continue the work of Takao Komatsu by considering the inhomogeneous approximation constant L(θ,ϕ) for Hurwitzian numbers θ, and rationally related ϕ(r θ+m)/n in Q(θ) +Q. The current work uses a compactness theorem to relate such inhomogeneous constants to the homogeneous approximation constants. Among the new results are: a characterization of such pairs θ,ϕfor which L(θ,ϕ) is zero; consideration of small values of n^2 L(e^{2/s},ϕ); and the proof of a conjecture of Komatsu.
