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.

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 …
