报告摘要

We study linear diferential equations with exponential polynomial coeffcients, where exactly one coeffcient is of order greater than all the others. The main result shows that a nontrivial exponential polynomial solution of such an equation has a certain dual relationship with the maximum order coe_cient. Several examples illustrate our results and exhibit possibilities that can occur.This presentation is based on a very recent joint work with Gary Gundersen and Zhi-Tao Wen.
