A double epidemic model for the SARS propagation

TW Ng, G Turinici, A Danchin - BMC Infectious diseases, 2003 - Springer
Background An epidemic of a Severe Acute Respiratory Syndrome (SARS) caused by a new
coronavirus has spread from the Guangdong province to the rest of China and to the world, …

The squeezing function on doubly-connected domains via the Loewner differential equation

TW Ng, CC Tang, J Tsai - Mathematische Annalen, 2021 - Springer
For any bounded domains $$\varOmega $$ Ω in $${\mathbb {C}}^{n}$$ C n , Deng, Guan
and Zhang introduced the squeezing function $$S_\varOmega (z)$$ S Ω ( z ) which is a …

Meromorphic solutions of higher order Briot–Bouquet differential equations

AE Eremenko, L Liao, TW Ng - Mathematical Proceedings of the …, 2009 - cambridge.org
For differential equations P (y (k), y)= 0, where P is a polynomial, we prove that all
meromorphic solutions having at least one pole are elliptic functions, possibly degenerate.

[HTML][HTML] A new transmission route for the propagation of the SARS-CoV-2 coronavirus

A Danchin, TW Ng, G Turinici - Biology, 2020 - mdpi.com
Simple Summary In animals, two dominant organs are infected by coronaviruses, the
respiratory tract and the gut. In past epidemics, a shift from the lung to the gut or vice versa has …

Nonlinear Loewy factorizable algebraic ODEs and Hayman's conjecture

TW Ng, CF Wu - Israel Journal of Mathematics, 2019 - Springer
In this paper, we introduce certain n-th order nonlinear Loewy factorizable algebraic ordinary
differential equations for the first time and study the growth of their meromorphic solutions …

Entire solutions of differential equations that are related to trigonometric identities

GG Gundersen, WR Lü, TW Ng, CC Yang - Journal of Mathematical …, 2022 - Elsevier
We prove results concerning entire solutions of non-linear binomial differential equations
that have connections to trigonometric identities. We also prove a double inequality for the …

[HTML][HTML] Hypertranscendency of perturbations of hypertranscendental functions

J Huang, TW Ng - Journal of Mathematical Analysis and Applications, 2020 - Elsevier
Inspired by the work of Bank on the hypertranscendence of Γ e h where Γ is the Euler gamma
function and h is an entire function, we investigate when a meromorphic function f e g …

Ritt's theory on the unit disk

TW Ng, MX Wang - Forum Mathematicum, 2013 - degruyter.com
The aim of this paper is to revisit Ritt's theory from a topological perspective by extensively
using the concept of fundamental groups. This enables us to regard the theory as an example …

A companion matrix approach to the study of zeros and critical points of a polynomial

WS Cheung, TW Ng - Journal of mathematical analysis and applications, 2006 - Elsevier
In this paper, we introduce a new type of companion matrices, namely, D-companion matrices.
By using these D-companion matrices, we are able to apply matrix theory directly to study …
