Given a simple graph G,the oriented graph G^(σ)is obtained from G by orienting each edge and G is called the underlying graph of G^(σ).The skew-symmetric adjacency matrix S(G^(σ))of G^(σ),where the(u,v)-entry is 1...
Let A be a unital prime ∗*-algebra with a nontrivial projection.In this paper,it is proved that a mapΦ:A→A satisfiesΦ([A,B]⋄◦C)=[Φ(A),B]⋄◦C+[A,Φ(B)]⋄◦C+[A,B]⋄◦Φ(C)for all A,B,C∈A if and only ifΦis an additive ...

In this paper,we investigate some classes of skew polycyclic codes and polycyclic codes over R=Z_(4)[u]/.We first obtain the generator polynomials of all(1,2u)-polycyclic codes over R.Then,by defining some Gray maps,w...
Without specifying the structure of a time series,we model the distribution of a multivariate Markov process in discrete time by the corresponding multivariate Markov family and the one-dimensional flows of marginal d...

For a monoid M, we introduce the concept of skew strongly M-reversible rings which is a generalization of strongly M-reversible rings, and investigate their properties. It is shown that if G is a finitely generated Ab...
