Advances in computer power and software packages now make it possible to calculate molecular structure, properties, spectra, and reactivity with greater predictive power. Chemical processes, especially under conditions not readily available in the laboratory, can also be much more easily studied via theory and computations. In this environment, the concept of propagators (or Green's functions) is emerging as an increasingly useful tool in the study of atomic and molecular processes. Propagators in Quantum Chemistry, Second Edition presents the theory and basic approximations of propagators in a unified manner as it provides: * A thorough introduction to propagators, and how they can be used to study atomic and molecular properties and spectra * Updated examples and technical details of the use of the propagator concept in various common approximate treatments * Problems that provide the opportunity to work out further details and applications of the theory Propagators, which are still gaining acceptance as tools in theoretical chemistry, have a long-demonstrated power and success in a number of areas including condensed matter physics. Propagators in Quantum Chemistry clearly describes the unprecedented utility and value of propagators, and explores how and why they are becoming increasingly important to scientists and researchers across the scientific spectrum.Quantum chemistryMany-body problemPhysical & Theoretical ChemistryHILCCChemistryHILCCPhysical Sciences & MathematicsHILCCQuantum chemistry.Many-body problem.Physical & Theoretical ChemistryChemistryPhysical Sciences & Mathematics541/.28Linderberg Jan48840Öhrn YngveèOhrn YngvePQKBBOOK9911020189103321Propagators in Quantum Chemistry339433UNINA02909nam 2200421 u 450 991104913980332120260211195938.097808156569060815656904(CKB)28159779800041(VLeBooks)9780815656906(Perlego)4433604(EXLCZ)992815977980004120230909d2023uuuu uy 0engur|||||||||||Urgency of Indigenous ValuesSyracuse University Press20231 online resource (1 p.)9780815638087 Collaborations in the Heartland of the Haudenosaunee : Determining an Interpretive Location -- Indigenous Values -- Paying Attention -- Habitation -- Exchange -- Discovery and Indigeneity -- Value Change for Survival.In this book, Philip Arnold utilizes a collaborative method, derived from the Two-Row Wampum (1613) and his 40 year relationship with the Haudenosaunee, in exploring the urgent need to understand Indigenous values, support Indigenous Peoples, and to offer a way toward humanitys survival in the face of ecological and environmental catastrophe. Indigenous values connect human beings with the living natural world through ceremonial exchange practices with non-human beings who co-inhabit the homelands. Arnold outlines Indigenous traditions of habitation and ceremonial gift economies and contrasts those with settler-colonial values of commodification where the land and all aspects of material life belongs to human beings and are reduced to monetary use-value.Through an examination of the Doctrine of Christian Discovery, a series of fifteenth-century documents that used religious decrees to justify the subjugation and annihilation of Indigenous Peoples, Arnold shows how issues such as environmental devastation, social justice concerns, land theft, and forced conversion practices have their origins in settler-colonial relationships with the sacredthat persists today. Designed to initiate a conversation in the classroom, in the academy, and in various communities about what is essential to the category of Indigeneity, this book offers a way of understanding value systems of Indigenous peoples. By pairing the concepts of Indigeneity and religion around competing values systems, Arnold transforms our understanding of both categories.Indian philosophyValuesSpiritualityIroquois IndiansReligionIndigenous peoplesReligionIndian philosophy.Values.Spirituality.Iroquois IndiansReligion.Indigenous peoplesReligion.299.7Arnold Philip P.1957-1891777BOOK9911049139803321Urgency of Indigenous Values4536016UNINA
