abstract: in the paper of black and scholes (1973) a closed form solution for the price of a european option is derived . as extension to the black and scholes model with constant volatility, option pricing model with time varying volatility have been suggested within the frame work of generalized autoregressive conditional heteroskedasticity (garch) . these processes can explain a number of em...

In this paper, we propose two numerical schemes for solving a nonlinear level set equation on unstructured triangulations. The consistency and the stability of these schemes are shown. In addition, we show how to compute nodewise fisrt and second order derivatives. An application example of curve construction using these approximations is provided to demonstrate their accuracy. Résumé. Dans ce ...

In [59], periodic minimal surfaces in a medium with exclusions (voids) are constructed and in this paper we present two algorithms for computing these minimal surfaces. The two algorithms use evolution of level sets by mean curvature. The first algorithm solves the governing nonlinear PDE directly and enforces numerically an orthogonality condition that the surfaces satisfy when they meet the b...
