Outline of Final Research Achievements |
We clarified a scale invariance structure of the critical Hardy inequality. Namely, we proved that the higher order remainder term is automatically determined by the scale invariance property. Moreover, we investigated classification results of existence and nonexistence of the heat equation with general nonlinearity, and proved its threshold integrability of the initial data. In addition, if the nonlinear term is an exponential type, we obtained the classification of uniqueness and non uniqueness results.
