The same problem is considered in [6, 17]; our approach can be much more direct in the view of the triangularity structure of the adjacency matrix.
By assuming the triangularity of the adjacency matrix that represents the mutual citations we proved certain common features of this kind of hyperlinked environment, for example, that the insertion of a new citation can only increase the rank of the newly cited paper.

First introduced in Macdonald (1988), Macdonald polynomials are often defined as the set of q, t-symmetric functions that satisfy certain orthogonality and triangularity conditions, as is well described in Macdonald (1995).
This triangularity property, together with the fact that they form an orthonormal basis with respect to Hall scalar product, determines entirely the Schur functions.
