Betti Numbers of the Moduli Space of Rank 3 Parabolic Higgs Bundles
Parabolic Higgs bundles on a Riemann surface are of interest for many reasons, one of them being their importance in the study of representations of the fundamental group of the punctured surface in the complex general linear group. in this paper the authors calculate the Betti numbers of the moduli space of rank 3 parabolic Higgs bundles with fixed and non-fixed determinant, using Morse theory. A key point is that certain critical submanifolds of the Morse function can be identified with moduli spaces of parabolic triples. These moduli spaces come in families depending on a real parameter and the authors carry out a careful analysis of them by studying their variation with this parameter. Thus the authors obtain in particular information about the topology of the moduli spaces of parabolic triples for the value of the parameter relevant to the study of parabolic Higgs bundles. The remaining critical submanifolds are also described: one of them is the moduli space of parabolic bundles, while the rem
Moduli Spaces and Vector Bundles—New Trends
This volume contains the proceedings of the VBAC 2022 Conference on Moduli Spaces and Vector Bundles—New Trends, held in honor of Peter Newstead's 80th birthday, from July 25–29, 2022, at the University of Warwick, Coventry, United Kingdom. The papers focus on the theory of stability conditions in derived categories, non-reductive geometric invariant theory, Brill-Noether theory, and Higgs bundles and character varieties. The volume includes both survey and original research articles. Most articles contain substantial background and will be helpful to both novices and experts.
Human Rights in the Digital Age
The digital age began in 1939 with the construction of the first digital computer. In the sixty-five years that have followed, the influence of digitisation on our everyday lives has grown steadily and today digital technology has a greater influence on our lives than at any time since its development. This book examines the role played by digital technology in both the exercise and suppression of human rights. The global digital environment has allowed us to reinterpret the concept of universal human rights. Discourse on human rights need no longer be limited by national or cultural boundaries and individuals have the ability to create new forms in which to exercise their rights or even to ...
Hero with an African Face
Drawing on extensive research and his own wide travels, Ford vividly retells ancient African myths and tales and brings to light their universal meanings.
Derek Walcott, The Journeyman Years, Volume 1: Culture, Society, Literature, and Art
During the same period in which Derek Walcott was pouring immense physical, emotional, and logistical resources into the foundation of a viable first-rate West Indian theatre company and continuing to write his inimitable poetry, he was also busy writing newspaper reviews, chiefly for the Trinidad Guardian. His prodigious reviewing activity extended far beyond those areas with which one might most readily associate his interests and convic¬tions. As Gordon Rohlehr once prescient¬ly observed, “If one wants to see a quoti¬dian workaday Walcott, one should go back to [his] well over five hundred arti¬cles, essays and reviews on painting, cinema, calypso, carnival, drama and lite¬rature,â...
Homeless Heritage
Homeless Heritage describes the process of using archaeological methodologies to collaboratively document how contemporary homeless people use and experience the city. Drawing on fieldwork undertaken in Bristol and York, the book first describes the way in which archaeological methods and theory have come to be usefully applied to the contemporary world, before exploring the historical development of the concept of homelessness. Working with homeless people, the author undertook surveys and two excavations of contemporary homeless sites, and the team co-curated two public heritage exhibitions - with surprising results. Complementing a growing body of literature that details how collaborative and participatory heritage projects can give voice to marginalised groups, Homeless Heritage details what it means to be homeless in twenty-
