Absolute homogene-ity follows from (3.1) since (3.6) k uk2 = h u; ui= j j2kuk2: So, it is only the triangle inequality we need. This follows from the next lemma, which is the Cauchy-Schwarz inequality in this setting { (3.8). Indeed, using the WebDec 6, 2024 · In this study, a multiparameter Hardy–Hilbert-type inequality for double series is established, which contains partial sums as the terms of one of the series.
