A model of the options pricing and hedging methodology, taking into account the execution costs and market influence, related to nonlinear Black — Scholes equations, is considered. Invariant solutions are found for two-dimensional subalgebras of the five-dimensional Lie algebra of the equation under study.
Keywords: options pricing, hedging, Black — Scholes type equation, Guéant — Pu model, Lie algebra, invariant solution.
