Thick, syndetic, and piecewise syndetic subsets of Fräıssé structures
We define and undertake a systematic study of thick, syndetic, and piecewise syndetic subsets of a Fräıssé structure. Each of these collections forms a family in the sense of Akin and Glasner [AG], and we define and study ultrafilters on each of these families, paying special attention to ultrafilters on the thick sets. In the process, we generalize many results of Bergelson, Hindman, and McCut...
متن کاملA Universal Constant for Exponential Riesz Sequences
The aim of this paper is to study certain correlations between lower and upper bounds of exponential Riesz sequences, in particular between sharp lower and upper bounds, where we show that the product of the sharp bounds of an exponential Riesz sequence is bounded from above by a universal constant. The result is applied to the norms of coefficient and frame operators and their inverses.
متن کاملSN̈AP: SyNdetic Assistance Processes
Activity recognition in intelligent environments could play a key role for supporting people in their activities of daily life. Partially observable Markov decision process (POMDP) models have been used successfully, for example, to assist people with dementia when carrying out small multi-step tasks such as hand washing. POMDP models are a powerful, yet flexible framework for modeling assistan...
متن کاملΔ-quasi-slowly Oscillating Sequences in Locally Normal Riesz Spaces
In this paper, we introduce the notion of δ-quasi-slowly oscillating sequences, study on δ-quasi-slowly oscillating compactness and δ-quasi-slowly oscillating continuous functions in locally normal Riesz space.
متن کاملUniform Partitions of Frames of Exponentials into Riesz Sequences
The Feichtinger Conjecture, if true, would have as a corollary that for each set E ⊂ T and Λ ⊂ Z, there is a partition Λ1, . . . ,ΛN of Z such that for each 1 ≤ i ≤ N , {exp(2πixλ) : λ ∈ Λi} is a Riesz sequence. In this paper, sufficient conditions on sets E ⊂ T and Λ ⊂ R are given so that {exp(2πixλ)1E : λ ∈ Λ} can be uniformly partitioned into Riesz sequences.
