On Abelian group representability of finite groups
A set of quasi-uniform random variables X1, . . . , Xn may be generated from a finite group G and n of its subgroups, with the corresponding entropic vector depending on the subgroup structure of G. It is known that the set of entropic vectors obtained by considering arbitrary finite groups is much richer than the one provided just by abelian groups. In this paper, we start to investigate in mo...
متن کاملOn Skew Cyclic Codes over a Finite Ring
In this paper, we classify the skew cyclic codes over Fp + vF_p + v^2F_p, where p is a prime number and v^3 = v. Each skew cyclic code is a F_p+vF_p+v^2F_p-submodule of the (F_p+vF_p+v^2F_p)[x;alpha], where v^3 = v and alpha(v) = -v. Also, we give an explicit forms for the generator of these codes. Moreover, an algorithm of encoding and decoding for these codes is presented.
متن کاملAdditive Representability of Finite Measurement Structures
In this survey we will concentrate on recent developments of Peter Fishburn’s ideas in representational theory of finite measurement structures, where he saw a gap in understanding of additive representability of preferences. He made a significant contribution to this theory and formulated a large number of open problems, which will undoubtedly guide future investigators. Only a few of Fishburn...
متن کاملon annihilator graph of a finite commutative ring
the annihilator graph $ag(r)$ of a commutative ring $r$ is a simple undirected graph with the vertex set $z(r)^*$ and two distinct vertices are adjacent if and only if $ann(x) cup ann(y)$ $ neq $ $ann(xy)$. in this paper we give the sufficient condition for a graph $ag(r)$ to be complete. we characterize rings for which $ag(r)$ is a regular graph, we show that $gamma (ag(r))in {1,2}$ and...
متن کاملOn the Zero-divisor Cayley Graph of a Finite Commutative Ring
Let R be a fnite commutative ring and N(R) be the set of non unit elements of R. The non unit graph of R, denoted by Gamma(R), is the graph obtained by setting all the elements of N(R) to be the vertices and defning distinct vertices x and y to be adjacent if and only if x - yin N(R). In this paper, the basic properties of Gamma(R) are investigated and some characterization results regarding co...
