Advanced Computational Algorithms

10:00 AM-12:00 PM
Lehua (Salon 6)

Much attention has been paid to the development of accurate, efficient and robust computational methods in the last a few decades. However, finding numerical solutions for partial differential equations is still a challenge owing to the presence of possible singularities and/or homoclinic manifolds that induce sharp transitions in the solutions.For example, difficulties exist in shock wave analysis and in the conservation of a Hamiltonian system involving homoclinic orbits. The speakers in this minisymposium will address new developments in shock capturing and symplectic algorithms.
