Regularity of solutions of a free boundary problem modeling the growth of solid tumors
Free boundary problem tumor model regularity
2011/10/15
In this paper we study a free boundary problem modeling the growth of solid tumors. Due to the free boundary and surface tension effects, this problem is a nonlinear problem involving non-local terms....
On a free boundary problem for an American put option under the CEV process
free boundary problem American put option CEV process
2010/12/7
We consider an American put option under the CEV process. This corre-sponds to a free boundary problem for a PDE. We show that this free boundary satises a nonlinear integral equation, and analyze it...
