| Outline of Final Research Achievements |
In this research project, we studied irregular version of the conformal field theory and Painleve equations. Using representation theory of Virasoro algebra, we defined irregular vertex operators and irregular conformal blocks. Using these irregular conformal blocks, we proved Fourier expansion formulas at infinity of the tau functions of the fourth and fifth Painleve equations and gave conjectural Fourier expansion formulas of the tau functions of the second and third Painleve equations.
