On the class of square Petrie matrices induced by cyclic permutations by Bau-Sen Du

“…In this paper, we show that if σ is a cyclic permutation on P, then all such matrices Aσ are similar to one another over Z2 (but not over Zp for any prime p≥3) and their characteristic polynomials over Z2 are all equal to ∑k=0nxk. …”

Fiscal function of taxes, its impact on budget revenues at various levels by N. Z. Zotikov

“…Currently, in economics there is no single, well-established point of view on the number of functions performed by the tax. At the same time, all researchers are unanimous in their opinion that the main function is the fiscal function, according to which the revenue base of budgets of all levels is formed at the expense of taxes. …”

Schatten's theorems on functionally defined Schur algebras by Pachara Chaisuriya, Sing-Cheong Ong

“…For each triple of positive numbers p,q,r≥1 and each commutative C*-algebra ℬ with identity 1 and the set s(ℬ) of states on ℬ, the set 𝒮r(ℬ) of all matrices A=[ajk] over ℬ such that ϕ[A[r]]:=[ϕ(|ajk|r)] defines a bounded operator from ℓp to ℓq for all ϕ∈s(ℬ) is shown to be a Banach algebra under the Schur product operation, and the norm ‖A‖=‖|A|‖p,q,r=sup{‖ϕ[A[r]]‖1/r:ϕ∈s(ℬ)}. …”

Commutativity theorems for rings with constraints on commutators by Hamza A. S. Abujabal

“…In this paper, we generalize some well-known commutativity theorems for associative rings as follows: Let n>1, m, s, and t be fixed non-negative integers such that s≠m−1, or t≠n−1, and let R be a ring with unity 1 satisfying the polynomial identity ys[xn,y]=[x,ym]xt for all y∈R. Suppose that (i) R has Q(n) (that is n[x,y]=0 implies [x,y]=0); (ii) the set of all nilpotent elements of R is central for t>0, and (iii) the set of all zero-divisors of R is also central for t>0. …”
