โœฆ Synopsis


Let X 1 ; X 2 ; : : : ; be a sequence of i.i.d. random variables. X j ; j 6 n is called a near-maximum i X j falls within a distance of the maximum M n = max{X 1 ; : : : ; X n }. In this paper, we focus on medium tailed distributions. A useful relationship on the number of near-maxima is built between general medium tailed and exponential distributions. Limit properties of the ratio S n (a)=S n are discussed, where S n (a) is the sum of near-maxima.

Central and local limit theorems are derived for the number of distinct summands in integer partitions, with or without repetitions, under a general scheme essentially due to Meinardus. The local limit theorems are of the form of Crame rtype large deviations and are proved by Mellin transform and th

In this paper, we establish a new limit theorem for partial sums of random variables. As corollaries, we generalize the extended Borel-Cantelli lemma, and obtain some strong laws of large numbers for Markov chains as well as a generalized strong ergodic theorem for irreducible and positive recurrent

In this paper we give an extension of the convergence theorem for martingales which are bounded in L, norm. This theorem is used to obtain the law of large numbers under dependent assumptions.
