Research on the properties (existence, order of growth, zeros, poles and fixed points, etc.) of solutions of differential equations in a complex domain and in the unit disc is very important. There has been a fast development in this field and many significant results have been obtained since the 1980s.
In the present text, I. Laine studies and lists many recent results on the growth and value distribution of meromorphic solutions of complex differential equations in the complex plane and in the unit disc, which are not to be found in books such as:
[1] [I. Laine, Nevanlinna theory and complex differential equations. de Gruyter Studies in Mathematics. 15. Berlin: W. de Gruyter (1992; Zbl 0784.30002)].
[2] [G. Jank and L. Volkmann, Einführung in die Theorie der ganzen und meromorphen funktionen mit Anwendungen auf Differentialgleichungen. UTB für Wissenschaft, Große Reihe. Basel etc.: Birkhäuser (1985; Zbl 0682.30001)].
In this text, I. Laine presents results under the following five aspects: 7mm
local theory of complex differential equations;
linear differential equations in the complex plane;
linear differential equations in unit disc;
nonlinear differential equations in the complex plane;
algebroid solutions of complex differential equations.
This work could be very important to researchers in the field of complex differential equations.
