Section " 1 - Application of Eigenvalues and Eigenvectors: Navigating Webpages" describes a transition matrix for discrete dynamic system.

This includes " A linear transformation, defined by a matrix 𝑃, will have entries 𝑝𝑖𝑗 with the probabilities that the browser navigates to page 𝑗 from page 𝑖 . For fixed column 𝑗 , the entries represent a probability distribution describing location of the browser at the next step, given that you are at state 𝑗"

I believe this should read "…given that you are at state 𝑖 ", correct?

To make easier to read, the below quote capitalizes index β€œJ”:
" A linear transformation, defined by a matrix 𝑃, will have entries 𝑝𝑖J with the probabilities that the browser navigates to page 𝑗 from page J . For fixed column 𝑗 , the entries represent a probability distribution describing location of the browser at the next step, given that you are at state J"

Thanks, John

Yes, I think you are correct.

Thanks for pointing out this issue.
