| Research Abstract |
We studied some kinds of bound graphs from the point of view of clique covers, order ideals and intervals. Using properties of sets of maximal elements and sets of minimal elements of posets, we obtain some properties of strict-semi-bound graphs.
And we consider strict-double-bound numbers which are the number of isolated vertices with clique covers and estimate strict-double-bound numbers of some families of graphs.
