Digraphs and cycle polynomials for free-by-cyclic groups

Yael Algom-Kfir, Eriko Hironaka, Kasra Rafi

Dowdall, Kapovich and Leininger developed an analog of fibered face theory for fully irreducible, atoroidal free group outer automorphisms. In this paper, we develop an analog of McMullen's Teichmueller polynomial in this setting.
