There is a quite definite number of field-rotation parameters determining the bifurcations of multiple limit cycles in the polynomial systems, and in some cases, for example,

The talk covered practically all directions of mathematical thought of that time and contained a list of 23 problems which determined the further development of mathema- tics in many respects (1, 119]. Hilbert‘s Sixteenth Problem (the second part) was stated as follows

事與愿違

Radiation Experimental Results, obtained results and applying the Wintner-Perko termination principle for multiple limit cycles, we suggest a new (global) approach to the solution of Hilbert’s Sixteenth Problem in the case of quadratic systems. This approach can be applied also to cubic and more general polynomial systems.
