Polynomial control on weighted stability bounds and inversion norms of localized matrices on simple graphs
Qiquan Fang, Chang Eon Shin, Qiyu Sun
The (un)weighted stability for some matrices is one of essential hypotheses in time-frequency analysis and applied harmonic analysis. In the first part of this paper, we show that…
