<abstract xmlns="http://www.w3.org/1999/xhtml">In 2009, Grant, Shallit, and Stoll [Acta Arith. <bold>140</bold> (2009), [345–368] constructed a large family of pseudorandom sequences, called generalized Rudin--Shapiro sequences, for which they established some results about the average of discrete correlation coefficients of order 2 in cases where the size of the alphabet is a prime number or a squarefree product of primes. We establish similar results for an even larger family of pseudorandom sequences, constructed via difference matrices, in the case of an alphabet of any size. The constructions generalize those from Grant et al. In the case where the size of the alphabet is squarefree and where there are at least two prime factors, we obtain an improvement in the error term by comparison with the result of Grant et al.</abstract>

A Class of Littlewood Polynomials that are Not <italic>L</italic><italic>α</italic>-Flat

Notes on the Distribution of Roots Modulo a Prime of a Polynomial III

<abstract xmlns="http://www.w3.org/1999/xhtml">The basic goal of quantization for probability distribution is to reduce the number of values, which is typically uncountable, describing a probability distribution to some finite set and thus approximation of a continuous probability distribution by a discrete distribution. Mixtures of probability distributions, also known as mixed distributions, are an exciting new area for optimal quantization. In this paper, we investigate the optimal quantization for three different mixed distributions generated by uniform distributions associated with probability vectors.</abstract>
