Recently ideas based on Feynman path integrals have also played an important role in areas of mathematics like low dimensional topology and differential geometry, algebraic geometry, infinite dimensional analysis and geometry, and number theory. The 2nd edition of LNM 523 is based on the two first authors' mathematical approach of this theory presented in its 1st edition in 1976. To take care of the many developments which have occurred since then, an entire new chapter about the current forefront of research has been added. Except for this new chapter, the basic material and presentation of the first edition was mantained, a few misprints have been corrected. At the end of each chapter the reader will also find notes with further bibliographical information.Lecture notes in mathematics (Springer-Verlag) ;523.Differential equations, PartialFeynman integralsPath integralsDifferential equations, Partial.Feynman integrals.Path integrals.515.35381Q30mscAlbeverio S.

Using an ethnographic historical approach and drawing on the intricacies of what it has meant to be and belong in Kom- an ethnic community in the Northwest Region of Cameroon - since 1800, he explores the discourses and practices of kfaang as central to any understanding of mobility and modernity in Kom, Cameroon and Africa at large. The book unveils the emic understanding of modernity through the history and ethnography of kfaang and its technologies and illustrates how these terminologies were conceived and perceived by the Kom people in their social and physical mobilities. It documents and analyzes the historical processes involved in bringing about and making kfaang a defining feature of everyday life in Kom and among Kom subjects.EthnologyCameroonEthnology967.11Nkwi Gam1534206MiAaPQMiAaPQMiAaPQBOOK9910797116603321African modernities and mobilities3781558UNINA
