Analytic solution of a nonlinear Black-Scholes equation
(2016)We study a nonlinear Black-Scholes partial differential equation whose nonlinearity is as a result of transaction costs that lead to market illiq- uidity. After reducing the equation into a nonlinear parabolic porous ... -
Analytic solution of a nonlinear Black-Scholes equation with price slippage
(2016)We study a nonlinear Black-Scholes partial differential equation whose nonlinearity is as a result of transaction cost and a price slippage impact that lead to market illiquidity with feedback effects. After reducing the ... -
Analytic solution of a nonlinear Black-Scholes partial differential equation
(2016)We study a nonlinear Black-Scholes partial differential equation whose nonlinearity is as a result of a feedback effect. This is an illiquid mar- ket effect arising from transaction costs. An analytic solution to the ... -
