Abstract

В статье доказано новое достаточное условие для равномерной интегрируемости экспоненциальных локальных мартингалов. Условие сформулировано в терминах квадратической вариации локального мартингала. Оно обобщает ряд известных достаточных условий подобного рода. In the article it is suggested a new sufficient condition for uniform integrability of continues exponential local martingales. It is shown that the condition is much weaker then a number of known sufficient conditions for uniform integrability of exponential local martingales.
