Xiang Chen, Liu Hong, Wu Huiqin, Ling Xu-dong · 2011
Based on the previous study and discussion, the coincidence degree theory and continuation theorem are applied to solve the existence of periodic solution to the two-dimensional time-varying delay Cohen-Grossberg in this paper. The study on two-dimension enables us to thick of a complete and clear pattern stored in memory from an incomplete or fuzzy pattern, and hence has a wide and bright application future in the pattern classification and identification. Therefore, studying two-dimension model brings more practical significance.
