英文摘要:
We consider a Black-Scholes type equation arising on a pricing model for a multi-asset option with general transaction costs. The pioneering work of Leland is thus extended in two different ways: on the one hand, the problem is multi-dimensional since it involves different underlying assets; on the other hand, the transaction costs are not assumed to be constant (i.e. a fixed proportion of the traded quantity). In this work, we generalize Leland\'s condition and prove the existence of a viscosity solution for the corresponding fully nonlinear initial value problem using Perron method. Moreover, we develop a numerical ADI scheme to find an approximated solution. We apply this method on a specific multi-asset derivative and we obtain the option price under different pricing scenarios.

中文摘要:
我们考虑一个Black-Scholes型方程,该方程产生于具有一般交易成本的多资产期权定价模型。因此,利兰的开创性工作以两种不同的方式展开:一方面,问题是多方面的,因为它涉及不同的基础资产;另一方面,交易成本不假定为常数(即交易量的固定比例)。在这项工作中,我们推广了Leland条件,并利用Perron方法证明了相应的完全非线性初值问题粘性解的存在性。此外,我们发展了一个数值ADI格式来寻找近似解。我们将此方法应用于一个特定的多资产衍生工具,并获得了不同定价场景下的期权价格。
