%0 Journal Article %T On a numerical approximation scheme for construction of the early exercise boundary for a class of nonlinear Black-Scholes equations %A Daniel Sevcovic %J Quantitative Finance %D 2010 %I arXiv %X The purpose of this paper is to construct the early exercise boundary for a class of nonlinear Black--Scholes equations with a nonlinear volatility depending on the option price. We review a method how to transform the problem into a solution of a time depending nonlinear parabolic equation defined on a fixed domain. Results of numerical computation of the early exercise boundary for various nonlinear Black--Scholes equations are also presented. %U http://arxiv.org/abs/1009.5973v2
