报告摘要:
We consider the following semilinear elliptic equation involving the fractional Laplacian
,
where , , is the -Laplacian and is the unit ball in . We first establish an optimal H\"{o}lder regularity estimate for solutions by using blow-up analysis and Liouville-type theorems. Subsequently, we give a convergence result for sequences of solutions with uniform H\"{o}lder continuity. These results are also used to show that the Hausdorff dimension of the rupture set
satisfies:
;
.
In particular, the latter one is a new phenomenon arising from the fractional Laplacian.
