1·î28Æü(ÌÚ) 15:00 -- 16:00 Dong Woo Sheen (Seoul National University, Korea) ``Fast Linear Solvers for Laplace Transformation Methods for Parabolic Problems" ¡ã¸¦µæÈ¯É½Í׻ݡä We begin with a brief review on the Laplace transformation methods for parabolic problems. After we take Laplace transforms of the parabolic problems in time, we solve the resulting complex-valued elliptic problems on a suitably chosen contour. The Laplace transformed elliptic problems are Helmholtz type. We will discuss some fast linear solvers for the set of complex-valued Laplace transformed elliptic problems. The the original time-domain solution is recovered by taking the Laplace inversion. Numerical results and applications will be given.
