We consider the problem of multiple sequence alignment under a xed evolu tionary tree given a tree whose leaves are labeled by sequences nd ancestral sequences to label its internal nodes so as to minimize the total length of the tree where the length of an edge is the edit distance between the sequences labeling its endpoints We present a new polynomial time approximation algorithm for this pr...

In (2003), we proved the injective homotopy exact sequence of modules by a method that does not refer to any elements of the sets in the argument, so that the duality applies automatically in the projective homotopy theory (of modules) without further derivation. We inherit this fashion in this paper during our process of expanding the homotopy exact sequence. We name the resulting doubly infin...
