This paper contains a construction for independent sets in the powers of the complements of odd cycles. In particular, we show that α ( C 2 2n+3 ) ≥ 22n + 1. It follows that for n ≥ 0 we have Θ(C2n+3) > 2, where Θ(G) denotes the Shannon capacity of graph G.
We consider Donovan's conjecture in the context of blocks groups G with defect group D and normal subgroups N◁G such that G=CD(D∩N)N, extending similar results for abelian groups. As an application we show holds form Q8×C2n or Q8×Q8 defined over a discrete valuation ring.
This paper provides the duality structure of the optimal two-block H∞ problem. The dual description leads naturally to a numerical solution based on convex programming for LTI (including infinite dimensional) systems. Alignment conditions are obtained and show that the optimal solution is flat in general, and unique in the SISO case. It is also proved that under specific conditions a wellknown ...

In this paper we will give some results on list T-colorings. In particular we will give a lower bound for the T-choice number of even cycles with the set T = {0, 1,2 ..... r}, r ~> 1, and give the value of the T-choice number for the even cycles C4, and C2n where n>~r.
This paper contains a construction for independent sets in the powers of odd cycles. It follows from this construction that the limit as n goes to infinity of n+ 1/2−Θ(C2n+1) is zero, where Θ(G) is the Shannon capacity of the graph G.
Cold cores in interstellar molecular clouds represent the very first phase in star formation. The physical conditions of these objects are studied in order to understand how molecular clouds evolve and how stellar masses are determined. The purpose of this study is to probe conditions in the dense, starless clump Ophichus D (Oph D). The ground-state (110 → 111) rotational transition of orthoH2D...
Let G×H denote the cartesian product of the graphs G and H , and Cn the cycle of order n. We prove the conjecture of Konig et al. that for n¿ 2, the minimum diameter of any orientation of the graph C3 × C2n+1 is n+ 3. c © 2001 Elsevier Science B.V. All rights reserved.
