报告摘要:In this talk, we display an evolving model on symmetric Lie algebras from a purely geometric way by using the Hamiltonian or para-Hamiltonian gradient flow of a fourth order functional called generalized bi-Schrodinger flows, which corresponds to the Fukumoto-Moffatt's model in the theory of the vortex filament in $R^3$. The theory of vortex filament in $R^3$ or $R^{2,1}$ up to the third-order approximation is generalized to symmetric Lie algebras in a unified way.
