چکیده

We present a Neumann-subproblem a posteriori "nite element procedure for the e$cient and accurate calculation of rigorous, `constant-freea upper and lower bounds for sensitivity derivatives of functionals of the solutions of partial di!erential equations. The design motivation for sensitivity derivative error control is discussed; the a posteriori "nite element procedure is described; the asymptotic bounding properties and computational complexity of the method are summarized; and illustrative numerical results are presented.

A Posteriori Finite Element Bounds for Sensitivity Derivatives of Partial–differential–equation Outputs

We present a Neumann-subproblem a posteriori finite element procedure for the efficient and accurate calculation of rigorous, “constant–free” upper and lower bounds for sensitivity derivatives of functionals of the solutions of partial differential equations. The design motivation for sensitivity derivative error control is discussed; the a posteriori finite element procedure is described; the ...

Pricing and hedging of financial derivatives using a posteriori error estimates and adaptive methods for stochastic differential equations

The e¢ cient and accurate calculation of sensitivities of the price of …nancial derivatives with respect to perturbations of the parameters in the underlying model, the so called ‘Greeks’, remains a great practical challenge in the derivative industry. This is true regardless of whether methods for partial di¤erential equations or stochastic di¤erential equations (Monte Carlo techniques) are be...

Estimation of diusion and convection coecients in an aerated hydraulic jump

Di€usion and convection coecients of the aerated ̄ow in a hydraulic jump are estimated in the framework of an optimal control problem. The speci®c gravity of air±water mixture is governed by a steady state convection di€usion partial di€erential equation. The governing equation includes the di€usion coecient and the convection coecient, which are taken as the control variables to minimize a ...

Accurate Parallel Integration of Large Sparse Systems of Di erential Equations

We describe a MIMD parallel code to solve a general class of ordinary di erential equations, with particular emphasis on the large, sparse systems arising from space discretization of systems of parabolic partial di erential equations. The main goals of this work are sharp bounds on the accuracy of the computed solution and exibility of the software. We discuss the sources of error in solving d...

Numerical Valuation of Cross-Currency Swaps and Swaptions

We investigate numerical valuation of cross-currency interest rate-based derivatives under Babbs' extended Vasicek-style model by numerical solution of the associated partial di erential equation (PDE) | in particular, we consider the terminable di erential (di ) swap. Firstly we precisely formulate, in terms of their cash ows, various types of single and cross-currency swaps and swaptions. We ...
