A vertex of a graph = () is said to be by $M \subseteq V$ if the majority of the elements of the neighborhood of (including itself) belong to . The set is a in if every vertex $i \in V$ is controlled by . Given a set $M \subseteq V$ and two graphs = ( $V, E_{1}$ ) and = ( $V, E_{2}$ ) where $E_{1} \subseteq E_{2}$ , the consists of deciding whether there exists a sandwich graph = () (, a graph where $E_{1} \subseteq E \subseteq E_{2}$ ) such that is a monopoly in = (). If the answer to the is No, we then consider the , whose objective is to find a sandwich...

About the decision of reachability for register machines

Similarity:

We study the decidability of the following problem: given affine functions ƒ,...,ƒ over $ℕ^{k}$ and two vectors $v_{1}, v_{2} \in ℕ^{k}$ , is reachable from by successive iterations of ƒ,...,ƒ (in this given order)? We show that this question is decidable for and undecidable for some fixed .

Cycle and Path Embedding on 5-ary N-cubes

RAIRO - Theoretical Informatics and Applications

Similarity:

We study two topological properties of the 5-ary -cube $Q_{n}^{5}$ . Given two arbitrary distinct nodes and in $Q_{n}^{5}$ , we prove that there exists an - path of every length ranging from to 5 - 1, where ≥ 2. Based on this result, we prove that $Q_{n}^{5}$ is 5-edge-pancyclic by showing that every edge in $Q_{n}^{5}$ lies on a cycle of every length ranging from to 5.

Structure of approximate solutions of variational problems with extended-valued convex integrands

Alexander J. Zaslavski (2008)

ESAIM: Control, Optimisation and Calculus of Variations

Similarity:

In this work we study the structure of approximate solutions of autonomous variational problems with a lower semicontinuous strictly convex integrand : × $\to$ $\cup$ ${\infty}$ , where is the -dimensional Euclidean space. We obtain a full description of the structure of the approximate solutions which is independent of the length of the interval, for all sufficiently large intervals.
