A precompact group topology $\tau$ on an abelian group $G$ is called {\em single sequence characterized} (for short, {\em ss-characterized}) if there is a sequence $\mathbf{u}= (u_n)$ in $G$ such that...
Abstract: In this paper, we use $\mathcal D$-split sequences and derived equivalences to provide formulas for calculation of higher algebraic $K$-groups (or mod-$p$ $K$-groups) of certain matrix subri...
The goal of this paper is to provide a link between the parameter spaces of two families of one-dimensional dynamical systems, and to shed some light onto some sets of numbers which arise as “exceptio...
In this paper, we provide criteria for fibre sequences of simplicial sheaves to be preserved by nullification. This generalizes a result of Berrick and Dror Farjoun and allows a better understanding o...
We give a new characterization of generalized B\"uchi sequences (sequences whose sequence of squares has constant second difference $(a)$, for some fixed integer $a$) of length 3 over the integers an...
We study Banach spaces satisfying some geometric or structural properties involving tightness of transfinite sequences of nested linear subspaces. These properties are much weaker than WCG and closely...
Let G = Cn1 . . .Cnr with 1 < n1 | . . . | nr be a finite abelian group, d(G) = n1+. . .+ nr −r, and let d(G) denote the maximal length of a zero-sum free sequence over G. Then d(G)  d(G),...
More Kolakoski Sequences      Kolakoski Sequences        2010/12/9
Our goal in this article is to review the known properties of the mysterious Kolakoski sequence and at the same time look at generalizations of it over arbitrary two letter alphabets. Our primary fo...
Assume that for some < 1 and for all nutural n a set Fn of at most 2 n “forbidden” binary strings of length n is fixed. Then there exists an infinite binary sequence ! that does not have (long) forb...
The ratio monotonicity of a polynomial is a stronger property than log-concavity. Let P(x) be a polynomial with nonnegative and nondecreasing coefficients. We prove the ratio monotone property of P(x ...
In this article we introduce the vector valued sequencespace $m(E_k, \phi, \Lambda)$, associated with the multipliersequence $\Lambda=(\lambda_k)$ of non-zero complex numbers, andthe terms of the sequ...
Negatively associated sequences have been studied extensively in recent years. Asymptotically negative association is a generalization of negative association. In this paper a Berry--Esseen theorem an...
Let $p=(p_{ k})_{k=0}^{\infty}$ be a bounded sequence of positive reals, $m\in{\Bbb N}$ and $u$ be s sequence of nonzero terms. If $x=(x_{k})_{k=0}^{\infty}$ is any sequence of complex numbers we writ...
Some maximal moment inequalities for partial sums of the strong mixing random variable sequence are established. These inequalities use moment sums as up-boundary and improve the corresponding ones ob...
In this paper, the congruence of feedforward monomial functions is defined, the sufficient and necessary condition on the congruence of non-degenerate monomials is given, and the number of non-equival...
