Comments on "Condensation of the digraph associated with a reciprocal matrix and a vector", arXiv:2607.10279
Susana Furtado, Charles Johnson
Since manuscript \cite{R}, recently posted on arXiv, is closely related to our previous work, we would like to clarify some facts about it. Namely, we would like to point out that…

Exact bounds for efficient consistent matrices obtained from a reciprocal matrix
Susana Furtado, Charles Johnson
For a given reciprocal matrix A, we give a union of matrix intervals in which any consistent matrix obtained from an efficient vector for A lies, and, conversely, any consistent ma…

Completions of pairwise comparison data that minimize the triad measure of inconsistency
Susana Furtado, Charles Johnson
We consider incomplete pairwise comparison matrices and determine exactly when they have a consistent completion and, if not, when they have a nearly consistent completion. We use…
