Pattern Frequency Sequences and Internal Zeros
Advances in Applied Mathematics, 2002 Consider the number of permutations in the symmetric group on n letters that contain c copies of a given pattern. As c varies (with n held fixed) these numbers form a sequence whose properties we study for the monotone patterns and the patterns 1, l, l-1, ..., 2. We show that, except for the patterns 1, 2 and 2, 1 where the sequence is well-known to be

Zero-sum balanced binary sequences
, 2012 For every positive integer n ≡ 0 mod 4, we construct a zero-sum {±1}-sequence of length n which is balanced, i.e., whose associated Steinhaus triangle contains as many +1’s as −1’s. This implies the existence of balanced binary sequences of every length m ≡ 0 or 3 mod 4, thereby providing a new solution to a problem posed by Steinhaus in 1963.

Sequences of reals to sequences of zeros and ones [PDF]
Proceedings of the American Mathematical Society, 1990 This paper considers maps from sequences of reals to sequences of zeros and ones which preserve the tail. The continuum hypothesis is used.

Electronic band gaps and transport in aperiodic graphene superlattices of Thue-Morse sequence
, 2012 We have studied the electronic properties in aperiodic graphene superlattices of Thue-Morse sequence. Although the structure is aperiodic, an unusual Dirac point (DP) does exist and its location is exactly at the position of the zero-averaged wave number

Primitive prime divisors in zero orbits of polynomials [PDF]
, 2011 Let $(b_n) = (b_1, b_2, ...)$ be a sequence of integers. A primitive prime divisor of a term $b_k$ is a prime which divides $b_k$ but does not divide any of the previous terms of the sequence. A zero orbit of a polynomial $f(z)$ is a sequence of integers

New Constructions of Zero-Correlation Zone Sequences [PDF]
IEEE Transactions on Information Theory, 2013 In this paper, we propose three classes of systematic approaches for constructing zero correlation zone (ZCZ) sequence families. In most cases, these approaches are capable of generating sequence families that achieve the upper bounds on the family size ($K$) and the ZCZ width ($T$) for a given sequence period ($N$).

On convergence of infinite matrix products with alternating factors from two sets of matrices
, 2018 We consider the problem of convergence to zero of matrix products $A_{n}B_{n}\cdots A_{1}B_{1}$ with factors from two sets of matrices, $A_{i}\in\mathscr{A}$ and $B_{i}\in\mathscr{B}$, due to a suitable choice of matrices $\{B_{i}\}$.
