This note presents a technical improvement to an upper bound in “The domination number of exchanged hypercubes” [Inform. Proc. Lett., 114 (2014) 159-162] by Klavžar and Ma.

This paper aims to show that the market selection hypothesis in finance is not solely driven by the competitiveness of such markets, as was originally claimed by Alchian [1] and Friedman [4]. Within a standard intertemporal General Equilibrium framework, we allow for an agent to have enough influence on financial markets to strategically affect prices of assets traded. We then show that, as in ...

In this article we give a new definition of direct product of two arbitrary fuzzy graphs. We define the concepts of domination and total domination in this new product graph. We obtain an upper bound for the total domination number of the product fuzzy graph. Further we define the concept of total α-domination number and derive a lower bound for the total domination number of the product fuzzy ...

We present a conjecture on the maximum number of edges of a graph that has a unique minimum dominating set. We verify our conjecture for some special cases and prove a weakened version of this conjecture in general. c © 2002 Elsevier Science B.V. All rights reserved.

In this paper, we give upper bounds on the upper signed domination number of [l, k] graphs, which generalize some results obtained in other papers. Further, good lower bounds are established for the minus ksubdomination number γ−101 ks and signed k-subdomination number γ −11 ks .
