摘要

本文关注如下抛物方程ht+hxxxx+xxhxα=fh_t+h_{xxxx}+\partial_{xx}|h_x|^\alpha=f中合适弱解的可能奇点集S\mathcal{S}的Hausdorff维数与非线性项参数α\alpha之间的精确关系。结果表明,当5/3α<7/35/3\leq\alpha<7/3时,S\mathcal{S}3α5α1\frac{3\alpha-5}{\alpha-1}维抛物Hausdorff测度为零,这推广了Oz\'anski和Robinson在[31,SIAM J. Math. Anal. 51: 228--255, 2019]中针对α=2\alpha=2f=0f=0的近期相应工作。同一结果对三维修正Navier-Stokes系统也成立。
