In this paper,we explore the refined semilattice of left C-wrpp semigroups,and show that a left C-wrpp semigroup S is a refined semilattice of left-R canceUativ
Let X1,X2,...,Xk be k disjoint subsets of S with the same cardinality m.Define H(m,k) = {X (C) S: X (C) Xi for 1 ≤I ≤k} and P(m,k) = {X (C) S : X ∩ Xi ≠φ f
In this paper,we give a general model of random walks in time-random environment in any countable space.Moreover,when the environment is independently identical
The short-range correlation between nucleons in finite nuclei is investigated in high energy protonnucleus and α-nucleus elastic scattering in the framework of
