Groups acting on graphs: Their automorphisms and their length functions
No full textActions on frees are powerful tools for understanding the structure of a group and its automorphisms. In this thesis, we generalise several existing results in this field to larger classes of groups.This is a three paper thesis; the main body of the work is contained in the following papers:[1] Matthew Collins. Fixed points of irreducible, displacement one automorphisms of free products. Preprint, May2023, available at arXiv:2305.01451.[2] Matthew Collins. Growth and displacement of free product automorphisms. Preprint, July 2023, available at arXiv:2307.13502.[3] Matthew Collins and Armando Martino. Length functions on groups and actions on graphs. Preprint, July 2023, available atarXiv:2307.10760.In [1], we prove that an irreducible, growth rate1 automorphism of a free product fixes a single point in outer space. This can be thought of as a generalisation of Dicks & Ventura’s classification of the irreducible, growth rate 1 automorphisms of free groups. It is well known for an irreducible free group automorphism that its growth rate is equal to the minimal Lipschitz displacement of its action on Culler-Vogtmann space. This follows as a consequence of the existence of train track representatives for the automorphism. In [2], we extend this result to the general - possibly reducible - case as well as to the free product situation where growth is replaced by ‘relative growth’. In [3], we study generalisations of Chiswell’s Theorem that 0-hyperbolic Lyndon length functions on groups always arise as based length functions of the group acting isometrically on a tree. We produce counter-examples to show that this Theorem fails if one replaces 0-hyperbolicitywith δ-hyperbolicity. We then propose a set of axioms for the length function on a finitely generated group that ensures the function is bi-Lipschitz equivalent to a (or any) length function of the group acting on its Cayley graph.</p

Moral Good, the Beatific Vision, and God’s Kingdom Writings by Germain Grisez and Peter Ryan, S.J.. Edited by Peter J. Weigel
No full textFor close to half a century, the work of Germain Grisez has been highly influential, and his writings continue to receive considerable attention from philosophers and theologians of diverse viewpoints. His co-author for this work is the professor and noted moral theologian Fr. Peter Ryan, S.J., currently the executive director of the Secretariat of Doctrine and Canonical Affairs of the United States Conference of Catholic Bishops (USCCB). These two eminent scholars explore fundamental questions about Christian eschatology, moral theory, the purpose of human life, and the promise of human fulfilment. The authors examine Christian teaching on the final destiny of persons, investigating the meaning of God's kingdom, the hope of the beatific vision, and the centrality of moral goodness and divine grace in one's final end. This work is an ideal source for students, scholars, ministers and lay persons interested in basic questions of Christian theology, the philosophy of religion, ethical theory, and Catholic doctrin
