On the line following

“From orthonormality we have”, it seems the upper bound of the summation should be n.

after “A standard heuristic wavelet computation”: it seems that naively plugging in $I=J$ in the summation defining $c_{I,J}$ makes the expression $(\psi_I – \psi_J)^2$ equal to $0$ (interpreting squaring as taking the dot product of the vector with itself). It seems I am missing something simple — any help would be appreciated.
