Theorems on existence and global dynamics for the Einstein equations

This article is a guide to theorems on existence and global dynamics of solutions of the Einstein equations. It draws attention to open questions in the field. The local-in-time Cauchy problem, which is relatively well understood, is surveyed. Global results for solutions with various types of symmetry are discussed. A selection of results from Newtonian theory and special relativity that offer useful comparisons is presented. Treatments of global results in the case of small data and results on constructing spacetimes with prescribed singularity structure or late-time asymptotics are given. A conjectural picture of the asymptotic behaviour of general cosmological solutions of the Einstein equations is built up. Some miscellaneous topics connected with the main theme are collected in a separate section.Comment: Submitted to Living Reviews in Relativity, major update of Living Rev. Rel. 5 (2002)

Measurement of the very rare K+→π+ννˉK^+ \to \pi^+ \nu \bar\nu decay

The decay K+→π+νν¯ , with a very precisely predicted branching ratio of less than 10−10 , is among the best processes to reveal indirect effects of new physics. The NA62 experiment at CERN SPS is designed to study the K+→π+νν¯ decay and to measure its branching ratio using a decay-in-flight technique. NA62 took data in 2016, 2017 and 2018, reaching the sensitivity of the Standard Model for the K+→π+νν¯ decay by the analysis of the 2016 and 2017 data, and providing the most precise measurement of the branching ratio to date by the analysis of the 2018 data. This measurement is also used to set limits on BR(K+→π+X ), where X is a scalar or pseudo-scalar particle. The final result of the BR(K+→π+νν¯ ) measurement and its interpretation in terms of the K+→π+X decay from the analysis of the full 2016-2018 data set is presented, and future plans and prospects are reviewed

Civility: Its Uses and Abuses in Public Discourse

Decreased civility and increased polarization now characterize the public sphere in ways that might have seemed unthinkable not long ago. The bonds of civic community have become frayed in recent years. Too often we seem unable to engage with one another in meaningful ways, especially when we disagree about foundational matters in morality, theology, and politics. How do we honor our civic responsibilities given this climate? Are there limits to tolerance and civility? What of the prophetic voices which urge us to respond to injustice, even when it causes discomfort? Join the Killeen Chair for Theology and Philosophy as we invite leading thinkers in philosophy and theology to help us negotiate these questions in order to move beyond simplistic dualism and toward true community

Debating same-sex marriage

Polls and election results show Americans sharply divided on same-sex marriage, and the controversy is unlikely to subside anytime soon. Debating Same-Sex Marriage provides an indispensable roadmap to the ongoing debate. Taking a point/counterpoint approach, John Corvino (a philosopher and prominent gay advocate) and Maggie Gallagher (a nationally syndicated columnist and co-founder of the National Organization for Marriage) explore fundamental questions: What is marriage for? Is sexual difference essential to it? Why does the government sanction it? What are the implications of same-sex marriage for children's welfare, for religious freedom, and for our understanding of marriage itself? While the authors disagree on many points, they share the following conviction: Because marriage is a vital public institution, this issue deserves a comprehensive, rigorous, thoughtful debate

Debating Religious Liberty and Discrimination

This book explores emerging conflicts about religious liberty and discrimination. In point-counterpoint format, it brings together longtime LGBT rights advocate John Corvino and rising conservative thinkers Ryan T. Anderson and Sherif Girgis to debate Religious Freedom Restoration Acts (RFRAs), anti-discrimination law, and age-old questions about identity, morality, and society.Cover -- Debating Religious Liberty and Discrimination -- Copyright -- Dedication -- Contents -- 1.
