The Kerr-Schild ansatz revised
No full text Kerr–Schild metrics have been introduced as a linear superposition of the flat spacetime metric and a squared null-vector field, say k, multiplied by some scalar function, say H. The basic assumption which led to Kerr solution was that k be both geodesic and shearfree. This condition is relaxed here and Kerr–Schild Ansatz is revised by treating Kerr–Schild metrics as exact linear perturbations of Minkowski spacetime. The scalar function H is taken as the perturbing function, so that Einstein's field equations are solved order-by-order in powers of H. It turns out that the congruence must be geodesic and shearfree as a consequence of third- and second-order equations, leading to an alternative derivation of Kerr solution. </jats:p

Introduction
No full textAotearoa New Zealand remains touted as an incredibly successful sporting nation despite its small population and arguably geographically remote location. Yet as the Introduction details, a range of challenges for sport and recreation lurk beneath the surface. Through providing an overview of the various chapters in the book, the Introduction outlines how Aotearoa New Zealand has a range of “legacy” issues, particularly in relation to race, ethnicity and gender, while being shaped by forms of tradition, myth, ritual and nostalgia, which many sports are needing to work through. Though there have been a range of government interventions through policies, these have largely been hampered by the strength of Aotearoa New Zealand’s neoliberal orientation. Collectively, the Introduction and the book as a whole metaphorically and symbolically criss-cross the New Zealand sport terrain to unearth some of these issues and tensions, both large and small, that undergird the contemporary sporting landscape
