چکیده
Let Km −H be the graph obtained from Km by removing the edges set E(H) of H where H is a subgraph of Km. We use the symbol A3 to denote P2 ∪K2. In this paper, we characterize the potentially K5 − P3, K5 −A3, K5 −K3 and K5 −K1,3-graphic sequences. Two characterizations of these imply two theorems due to Lai [11-12].

Let Km −H be the graph obtained from Km by removing the edges set E(H) of H where H is a subgraph of Km. In this paper, we characterize the potentially K5 − P3, K5 − A3, K5 −K3 and K5 − K1,3-graphic sequences where A3 is P2 ∪ K2. Moreover, we also characterize the potentially K5 − 2K2-graphic sequences where pK2 is the matching consisted of p edges.

For given a graph H , a graphic sequence π = (d1, d2, · · · , dn) is said to be potentially H-graphic if there exists a realization of π containing H as a subgraph. In this paper, we characterize the potentially K6 − C5 -graphic sequences .

For given a graphH , a graphic sequence π = (d1, d2, · · · , dn) is said to be potentially H-graphic if there exists a realization of π containing H as a subgraph. Let Km − H be the graph obtained from Km by removing the edges set E(H) where H is a subgraph of Km. In this paper, we characterize potentially K2,5-graphic sequences. This characterization implies a special case of a theorem due to ...

If T t = e Zt is a positive one-parameter contraction semigroup acting on l p (X) where X is a countable set and 1 ≤ p < ∞, then the peripheral point spectrum P of Z cannot contain any non-zero elements. The same holds for Feller semigroups acting on L p (X) if X is locally compact.

Let (M, g) be a compact Riemannian manifold of dimension n ≥ 3. We define the second Yamabe invariant as the infimum of the second eigenvalue of the Yamabe operator over the metrics conformal to g and of volume 1. We study when it is attained. As an application, we find nodal solutions of the Yamabe equation.
