1.In this paper,we proved that the total chromatic number and adjacent strong edge chromatic number of Cartesian product graph of cycle Cm and cycle C5n.证明了圈Cm与圈C5n的笛卡尔积图的全色数和邻强边色数都为5。 2.We study the star-edge coloring of Cartesian product graphs of some special...

We also see that the ones closed under bilimits are Dom and the Domn, for n⩾0. We also consider the standard three powerdomains [10]. Every domain D has a lower (Hoare) powerdomain PL(D), an upper (Smyth) powerdomain PU(D), and a convex (Plotkin) powerdomain PC(D). As PL...
