similar class
5.Besides,is independent of the choice of the finite glob-al absorbing set B_0.2)Let be a semigroup of class. Suppose that for each ,there isT_x≥0 such that then has a non-empty minimal closed global attractor,and for every t≥0,Besides,if all points in any closed F,which includes are positively Poisson Stable ,the Thre results similar to 1)and2)are given forthe semigroup of class 。
6.The paper does some discussions on the characteristic which the bounded variation sequence has. ft is found that the monotone sequence is colsely related to it, and very similar with the bounded variation functions, and reach the conclusion as follows: the class of bounded sequence ? the class of convergencal sequence ? the bounded variation sequence ? the hounded monotone sequence.
