A Note about the Black-Scholes Option Pricing Model under Time-Varying Conditions

Abstract

By solving the second-order parabolic partial differential equation, the BS option pricing formula can be obtained; The BS pricing model under time-varying conditions is hard to get an explicit solution; We found that there is a same mistake in Zhige Ren’s paper and Xiaochen Han’s paper, and trying to put forward an idea to solve a sort of second-order parabolic partial differential equations.
