Without specifying the structure of a time series,we model the distribution of a multivariate Markov process in discrete time by the corresponding multivariate
Let A be an abelian category,and (X,(Z),y) be a complete hereditary cotorsion triple.We introduce the definition of n-y-cotilting subcategories of A,and give a
