Abstract

The convergence of Hilbert-valued semimartingales to continuous semimartingales are discussed under the condition UT. And the stability of stochatic differential equations of type is discussed under jointly weak convergence of driving processes {(Yn, An)}n≥1, where Yn and An are H-valued semimartingale and H-valued finite variation with every component being increasing process, respectively.
