curprev 13:4713:47, 16 August 2024 141.99.250.10 talk 12,825 bytes −40 I deleted the last part of the equation $= \frac{b_{k+1}^\top b_k}{b_k^\top b_k}$ in the formula for the spectral radius, since there was an error. If one inserts the definition for $b_{k+1}$ here one notices that the normalization was missing. Another way to observe that this equation is false is by looking at the limit if $b_k$ converges. In this case the result would always have been 1. undo
