Subgroup Decomposition in $mathrm {Out}(F_n)$ (Memoirs of the American Mathematical Society)

About the Author Michael Handel, Lehman College, City University of New York, NY.Lee Mosher, Rutgers University, Newark, NJ. Product Description In this work the authors develop a decomposition theory for subgroups of $\mathsf{Out}(F_n)$ which generalizes the decomposition theory for individual elements of $\mathsf{Out}(F_n)$ found in the work of Bestvina, Feighn, and Handel, and which is analogous to the decomposition theory for subgroups of mapping class groups found in the work of Ivanov.
