Selected results of the theory of value distribution and growth of meromorphic functions

Ewa Ciechanowicz (2015)

Banach Center Publications

The paper discusses development of the theory of value distribution and growth of meromorphic functions, focusing on two basic notions: exceptional values and asymptotic values. Some historical context is given and contemporary achievements are presented. In particular, recent results concerning exceptional functions and asymptotic functions are considered.

Solutions méromorphes sur d’un système d’équations aux différences à coefficients constants et à deux pas récurrents

Jean-Claude Jolly (2002)

Annales de l’institut Fourier

On s’intéresse aux solutions méromorphes sur d’un système de deux équations aux différences à coefficients constants et à deux pas récurrents. Lorsqu’on fait varier ce système, les solutions décrivent une certaine algèbre 𝒟 [ s , t ] en rapport avec les fonctions elliptiques habituelles et celles de deuxième espèce de Hermite, ainsi que la fonction Z de Jacobi. Pour un système donné, les solutions trouvées forment sur le corps des fonctions elliptiques un espace vectoriel de dimension finie, en rapport...

Some further results on meromorphic functions that share two sets

Qi Han, Hong-Xun Yi (2008)

Annales Polonici Mathematici

This paper concerns the uniqueness of meromorphic functions and shows that there exists a set S ⊂ ℂ of eight elements such that any two nonconstant meromorphic functions f and g in the open complex plane ℂ satisfying E 3 ) ( S , f ) = E 3 ) ( S , g ) and Ē(∞,f) = Ē(∞,g) are identical, which improves a result of H. X. Yi. Also, some other related results are obtained, which generalize the results of G. Frank, E. Mues, M. Reinders, C. C. Yang, H. X. Yi, P. Li, M. L. Fang and H. Guo, and others.

Some results on the growth properties of Wronskians

Sanjib Kumar Datta, Arindam Jha (2009)

Archivum Mathematicum

The aim of this paper paper is to study the comparative growth properties of the composition of entire and meromorphic functions and wronskians generated by them improving some earlier results.
