On mean-periodicity

Mean-periodicity and Zeta Functions

This paper establishes new bridges between number theory and modern harmonic analysis, namely between the class of complex functions, which contains zeta functions of arithmetic schemes and closed with respect to product and quotient, and the class of mean-periodic functions in several spaces of functions on the real line. In particular, the meromorphic continuation and functional equation of t...

Periodicity properties on partial

The concept of periodicity has played over the years a centra1 role in the development of combinatorics on words and has been a highly valuable too1 for the design and analysis of algorithms. Fine and Wilf’s famous periodicity result, which is one of the most used and known results on words, has extensions to partia1 words, or sequences that may have a number of “do not know” symbols. These ext...

On Siebenmann Periodicity

Cappell and Weinberger gave a geometric interpretation of the Siebenmann periodicity phenomena. This near-periodicity on the structure sets of topological manifolds was originally demonstrated in an indirect way from the periodicity of the simply-connected quadratic L-groups, see Nicas and Siebenmann (1977). In particular it was shown for a topological manifold M , dim M ≥ 5, with structure set...
