We prove a number of conjectures recently stated by P. Barry, related to the paperfolding sequence and Rueppel sequence. Furthermore, we study regularity sequences involved in paper, that for all q≥2, consisting positive integers whose odd part is form 4k+1 not q-regular. Finally establish 2-regularity two Hankel determinants.

We propose a framework for solving equational and membership constraints for terms built over individual, sequence, function, and context variables and flexible arity symbols. Each membership constraint couples a variable with a regular expression on terms or contexts. There can be several membership constraints with the same constrained variable, and expressions may contain variables themselve...

A spectral sequence is constructed whose nonzero E1-terms are the Witt groups of the residue fields of a regular scheme X, arranged in Gersten-Witt complexes, and whose limit is the four global Witt groups of X. There are several immediate consequences concerning purity for Witt groups of low-dimensional schemes. The Witt groups of punctured spectra of regular local rings are also computed. Let...

In 1911, Steinhaus presented the following theorem: if A is a regular matrix then there exists a sequence of 0’s and 1’s which is not A-summable. In 1943, R. C. Buck characterized convergent sequences as follows: a sequence x is convergent if and only if there exists a regular matrix A which sums every subsequence of x. In this paper, definitions for “subsequences of a double sequence” and “Pri...
