Semistable Measures and Limit Theorems on Real and p-adic Groups.
Copulas are functions which join the margins to produce a joint distribution function. A special class of copulas called shuffles of Min is shown to be dense in the collection of all copulas. Each shuffle of Min is interpreted probabilistically. Using the above-mentioned results, it is proved that the joint distribution of any two continuously distributed random variables X and Y can be approximated uniformly, arbitrarily closely by the joint distribution of another pair X* and Y* each of which...
A generalization of the Poisson driven stochastic differential equation is considered. A sufficient condition for asymptotic stability of a discrete time-nonhomogeneous Markov process is proved.
A sequence of random elements is called strongly tight if for an arbitrary there exists a compact set such that . For the Polish space valued sequences of random elements we show that almost sure convergence of as well as weak convergence of randomly indexed sequence assure strong tightness of . For bounded Banach space valued asymptotic martingales strong tightness also turns out to the sufficient condition of convergence. A sequence of r.e. is said to converge essentially with...
