# Performance of the Thresholding Greedy Algorithm with Larger Greedy Sums

@inproceedings{Chu2022PerformanceOT, title={Performance of the Thresholding Greedy Algorithm with Larger Greedy Sums}, author={H{\`u}ng Việt Chu}, year={2022} }

A BSTRACT . The goal of this note is to study the performance of the Thresholding Greedy Algorithm (TGA) when we increase the size of greedy sums by a constant factor λ ≥ 1 . We introduce the so-called ( λ , partially greedy) bases. While the case λ = 1 gives strong partially greedy bases, we show that, for each λ > 1 , there exists a (Schauder) basis that is ( λ , partially greedy) but is not strong partially greedy. Furthermore, we investigate and give examples when a basis is (1) not 1…

We consider several greedy conditions for bases in Banach spaces that arise naturally in the study of the Thresholding Greedy Algorithm (TGA). In particular, we continue the study of almost greedy…

In this paper, motivated by the notion of $w$-Property $(A)$ defined in [2], we introduce the notions of $w$-left Property $(A)$ and $w$-right Property $(A)$. We also introduce the notions of…
