CI-groups with respect to ternary relational structures: new examples
نویسندگان
چکیده
We find a sufficient condition to establish that certain abelian groups are not CI-groups with respect to ternary relational structures, and then show that the groups Z3×Z2, Z7×Z2, and Z5 ×Z2 satisfy this condition. Then we completely determine which groups Z2 ×Zp, p a prime, are CI-groups with respect to color binary and ternary relational structures. Finally, we show that Z2 is not a CI-group with respect to ternary relational structures.

On the Cayley Isomorphism Problem for a Digraph with 24 Vertices
In this paper we are mainly concerned with the Cayley isomorphism problem for groups containing Q8. We prove that the group Q8 × C3 is not a CI-group with respect to colour ternary relational structures. Further, we prove that the non-nilpotent group C3 nQ8 is not a CI-group with respect to graphs.
متن کاملElicitation of the Groups and Group Cognitive Structures: An Application of Ternary Fuzzy Relational Products
The aim of this thesis is to extend the fuzzy relational product calculations from binary to ternary relations, and apply the ternary fuzzy relational product calculations to processing of the URBS data. It is demonstrated that, by ternary fuzzy relational product calculations, the respondents with the similar cognitive structures can be clustered into groups and cognitive structures of those g...
متن کاملRevenue - Profit Measurement in Data Envelopment Analysis with Dynamic Network Structures: A Relational Model
The correlated models are introduced in this article regarding revenue efficiency and profit efficiency in dynamic network production systems. The proposed models are not only applicable in measuring efficiency of divisional, periodical and overall efficiencies, but recognizing the exact sources of inefficiency with respect to revenue and profit efficiencies. Two numerical examples, consisting ...
متن کاملTemperature Tunability of Dielectric/ Liquid Crystal / Dielectric Photonic Crystal Structures
Recently, photonic crystals doped with liquid crystal (LC) material havegained much research interest. In this article new ternary one-dimensional photoniccrystal introduced and studied. The liquid crystal layer of 5CB and 5PCH is sandwichedby two dielectric layers. For the first time, we use four structures SiO2/UCF35/CaF2,SiO2/5CB/CaF2, NFK51/UCF35/NPSK53 and NFK51/5CB/NPSK53. The effect ofte...
متن کاملVisiting Some Relatives of Peirce's
The notion of a relational grammar is extended to ternary relations and illustrated by a fragment of English. Some of Peirce's terms for ternary relations are shown to be incorrect and corrected. Binary relations have been studied extensively by Peirce and Schrr oder in the nineteenth century, and in this century by Tarski and his students. No comparable attention has been paid to ternary relat...
