Tangential touch between free and fixed boundaries for the fully nonlinear Alt-Phillips problem
Yamin Wang, Hui Yu
For the fully nonlinear Alt-Phillips problem with parameter , we show that the free boundary intersects the fixed boundary tangentially where the Dirichlet data vanish.…

Free boundary regularity in nonlinear one-phase Stefan problem
Yamin Wang
We study the regularity of the free boundary in one-phase Stefan problem with nonlinear operator. Using the Hodograph transform and a linearization technique, we prove that flat fr…
