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…
Strong Partially Greedy Bases with respect to An Arbitrary Sequence
Hung Viet Chu
For Schauder bases, Dilworth et al. introduced and characterized the partially greedy property, which is strictly weaker than the (almost) greedy property. Later, Berasategui et al…
Extensions and new characterizations of some greedy-type bases
Miguel Berasategui, Pablo M. Berná, Hung Viet Chu
Partially greedy bases in Banach spaces were introduced by Dilworth et al. as a strictly weaker notion than the (almost) greedy bases. In this paper, we study two natural ways to s…
