Twisted conjugacy in dihedral Artin groups II: Baumslag Solitar groups BS(n,n)

In this second paper, we solve the twisted conjugacy problem for even dihedral Artin groups, that is, groups with presentation [Formula: see text], where [Formula: see text] is even, and [Formula: see text] is the word [Formula: see text] of length m. We then prove orbit decidability for the full automorphism group [Formula: see text], which then implies that the conjugacy problem is solvable in certain extensions of even dihedral Artin groups.
