摘要翻译：
我们考虑了一个具有短期资产的连续时间投资市场的随机博弈模型，研究了一种称为生存的策略，该策略保证使用这种策略的投资者的相对财富保持有界不为零。主要结果是得到了一个策略生存的充分条件，并证明了所有生存策略是渐近接近的。这也证明了一个生存战略允许一个投资者在一定意义上比竞争对手更快地积累财富。

英文摘要：
We consider a stochastic game-theoretic model of an investment market in continuous time with short-lived assets and study strategies, called survival, which guarantee that the relative wealth of an investor who uses such a strategy remains bounded away from zero. The main results consist in obtaining a sufficient condition for a strategy to be survival and showing that all survival strategies are asymptotically close to each other. It is also proved that a survival strategy allows an investor to accumulate wealth in a certain sense faster than competitors.
