报告内容:

In this talk,  two connection problems for the first Painlevé equation (PI) are considered. First, we classify the PI solutions asymptotically by the initial data, and build the limiting connection formulas between the parameters in the asymptotic behavior when the independent variable tends to negative infinity and the initial data. Second, the PI solutions are asymptotically classified again in terms of the location of the poles and the free parameter in their Laurent series.  As a by-product, we obtain the asymptotic behavior of the location of the n-th pole for the real tritronquée solution. Our main approach are based on  complex WKB or the method of “uniform asymptotics”. Finally, numerical simulations are carried out to verify our main results and to investigate some new heuristic properties of the PI solutions.
