摘要
In this paper we present a method which can transform a variational inequality with gradient constraints into a usual two obstacles problem in one dimensional case. The prototype of the problem is a parabolic variational inequality with the constraints of two first order differential inequalities arising from a two-dimensional model of European call option pricing with transaction costs. We obtain the monotonicity and smoothness of two free boundaries.
