| Abstract: | This paper is devoted to a new computational algorithm of numerical solution of B1ack-Scholes equation,applying the finite difference scheme and the orthonormal compactly supported wavelet transform approximarion.A new method is proposed to price American Put Options.Due to adaptive and vanishing moment property of wavelec basis,the difference operator and solution vector and wavelet series have sparseness in wavelet domain,decreasing computational complexity greatly. |
