In page rank can we make a node as sink that is having "n" inbound links but one outbound link to itself?
What is A+Z matrix for that?
I figured out that If there is any node with only one link to itself then we have to omit 1 in the column of A corresponding to that node.
But in Hub/Auth we can't omit that 1.
In page rank we have to omit that 1 otherwise A+Z will not be a stochastic matrix.
Page rank is independent of self links.
Is my inference correct?
