题目Title: Some problems about a family of linear functional differential equations

内容摘要Abstract： 

Given q between 0 and 1, one considers the following problems about the q-difference-differential equations y’(x)+ay(qx)+by(x)=f(x), where a and b are two numbers and f is a rational function:

(1) The pantograph equations following Kato and McLeod;

(2) The indexes of the associated operator d/dx+a σq+b;

(3) The connection formulas between zero and infinity;

(4) The asymptotic behavior of the solutions at infinity.

This talk is partially based on a joint work with H. Dai and G. Chen.
