A note on the law of large numbers for Banach space values asymptotic martingales;

According to the law of large numbers and variance analyses,a kind of Monte Carlo algorithm for computing triple integral was designed,and a proper random number was used to reduce theoretically variance to zero.

Local convergence and law of large numbers for Banach-space-valued amart are researched.

Discussed the laws of large numbers and convergence rate for B valued quasimartingale,these results generalize and extend some classical results.

In this paper, laws of large numbers for martingale difference like arrays in Banach spaces are investigated and related geometrical characterization of Banach spaces is discribed.

Complete convergence and law of large number of arrays of rowwise NQD random variables;

it is proved that law of large number for B-valued paraproduct martingale operator is valid under certain conditions.

Ushering in random variables,the essay uses the law of large number of probability to solve a type of limit issue of n-lay integration.
