报告题目:$L^p$ regularity theory for even order elliptic systems with antisymmetric first order potentials


摘要:In this talk, we are concerned with the optimal interior regularity theory to the system $$\Delta^{m}u=\sum_{l=0}^{m-1}\Delta^{l}\left\langle V_{l},du\right\rangle +\sum_{l=0}^{m-2}\Delta^{l}\delta\left(w_{l}du\right) +f \qquad \text{ in } B^{2m}.$$ Combining the conservation law established by Longueville-Gastel for homogeneous system and some new ideas together, we obtain optimal H\"older continuity and sharp $L^p$ regularity theory, similar to that of Sharp and Topping in two order case, for weak solutions to the above inhomogeneous system. Our results can be applied to study heat flow and bubbling analysis for polyharmonic mappings. This is a joint work with Prof. Chang-Yu Guo and Prof. Chang-Lin Xiang.
