This paper provides a theoretical foundation for the use of TAGs in phylogenetics. We provide a formal definition of TAG that - unlike previous definition - does not depend on the order in which input trees are provided. In the consensus case, when all input trees have the same leaf labels, we describe algorithms for constructing majority-rule and strict consensus trees using","authors_text":"David Fernandez-Baca, J.
