A matrix representation of phylogenetic trees

1997
In this paper we begin by describing two currently used methods for evaluating phylogenetic trees, one proposed by Fitch and Margoliash [5] and the other proposed by Saitou and Nei [7]. Both methods are heuristic in the sense that not all possible trees are tested to ensure that the best solution has been reached.

Finiteness Properties of Matrix Representations

The Annals of Mathematics, 1986
Let \(\Gamma_ n={\mathbb{Z}}[x_{ij}:\) \(i,j=1,...,n]\) be the polynomial ring in \(n^ 2\) variables with integer coefficients. For each polynomial \(\phi \in \Gamma_ n\) there is a map of \(M_ n(A)\), of the set of \(n\times n\) matrices over the commutative ring A with 1, into A, where to each matrix \([a_{ij}]\) there corresponds the element \(\phi (
