comment Eigenvalues of $\sum_{i=1}^n \frac{(x_i - x_{i-1})^2}{\lambda_i}$
Thanks. I knew that the determinant is $\prod_{i=1}^n\lambda_i^{-1}$ and I was guessing if that was the case for the eigenvalues.

revised Eigenvalues of $\sum_{i=1}^n \frac{(x_i - x_{i-1})^2}{\lambda_i}$
The first term should be $\frac{x_1^2}{\lambda_1}$

comment cryptography deciphering this text
Yes I know, that's why I said that it works only if you know in advance that this is a Caesar cipher. To decipher with Vigenère substitution one should look for patterns in the text, same idea but little more complicated.
