On consecutive greedy and other greedy-like type of bases
Miguel Berasategui, Pablo M. Berná, Hung Viet Chu
We continue our study of the Thresholding Greedy Algorithm when we restrict the vectors involved in our approximations so that they either are supported on intervals of …
Approximation by Egyptian Fractions and the Weak Greedy Algorithm
Hung Viet Chu
Let . A sequence of positive integers is called a weak greedy approximation of if . We introduce the weak g…
Schreier families and -(almost) greedy bases
Kevin Beanland, Hung Viet Chu
Let be a hereditary collection of finite subsets of . In this paper, we introduce and characterize -(almost) greedy bases. Given such a famil…
Linear recurrences of order at most two in nontrivial small divisors and large divisors
Hung Viet Chu, Kevin Huu Le, Steven J. Miller +2
For each positive integer , define $$S'_N \ =\ \{1 < d < \sqrt{N}: d|N\}\mbox{ and }L'_N \ =\ \{\sqrt{N} < d < N : d|N\}.$$ Recently, Chentouf characterized all positive integer…
The Thresholding Greedy Algorithm versus Approximations with Sizes Bounded by Certain Functions
Hung Viet Chu
Let be a Banach space and be a basis. For a function in a large collection (closed under composition), we define and characterize -gre…
Larger Greedy Sums for Reverse Partially Greedy Bases
Hung Viet Chu
An interesting result due to Dilworth et al. was that if we enlarge greedy sums by a constant factor in the condition defining the greedy property, then we obtain an equival…
