The seminal work of Black, Scholes, and Merton in 1973 gave rise to the celebrated Black-Scholes-Merton (BSM) model. The BSM model assumes that the underlying asset price ( S_t ) follows a geometric Brownian motion: [ dS_t = \mu S_t dt + \sigma S_t dW_t ] where ( \mu ) is the drift, ( \sigma ) the volatility, and ( dW_t ) a Wiener process (Brownian motion). Using Itô’s lemma and the no-arbitrage principle, one arrives at the Black-Scholes partial differential equation (PDE): [ \frac\partial V\partial t + \frac12\sigma^2 S^2 \frac\partial^2 V\partial S^2 + rS \frac\partial V\partial S - rV = 0 ] where ( V(S,t) ) is the option price and ( r ) is the risk-free interest rate. This PDE, with appropriate boundary conditions, has a closed-form analytical solution for European options—the famous Black-Scholes formula.
