Estimation of the Constant in a Burkholder Inequality for Supermartingales and Martingales
E. L. Presman Central Economics and Mathematics Institute, RAS
Abstract:
A Burkholder-type inequality for supermartingales and martingales is proved. The proof reduces to a refinement of the corresponding arguments by S. V. Nagaev, who obtained the inequality with a greater value of the upper bound.
Keywords:
expectation, martingale, supermartingale, Burkholder inequality, moments.
