On Qi’s Normalized Remainder of Maclaurin Power Series Expansion of Logarithm of Secant Function

Axioms
In the study, the authors introduce Qi’s normalized remainder of the Maclaurin power series expansion of the function lnsecx=−lncosx; in view of a monotonicity rule for the ratio of two Maclaurin power series and by virtue of the logarithmic convexity of

Normal spaces with prescribed Stone-Čech remainders [PDF]

Proceedings of the American Mathematical Society, 1992
It is shown that if X X is a locally compact Hausdorff space, then there is a normal space Y Y such that β Y ∖ Y ≅ X \beta Y\backslash Y \cong X . Examples are given of a countable nonsequential space, and a sequential nonlocally compact space, each of which ...

Normal forms with exponentially small remainder and Gevrey normalization for vector fields with a nilpotent linear part [PDF]

Annales de l'Institut Fourier, 2012
We explore the convergence/divergence of the normal form for a singularity of a vector field on ℂ n with nilpotent linear part. We show that a Gevrey-α vector field X with a nilpotent linear part can be reduced to a normal form of Gevrey-1+α type with the use of a Gevrey-1+α transformation.
