Web70 3. HILBERT SPACES Proof. The rst condition on a norm follows from (3.2). 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 Web8.
