Geometry and Billiards (Student Mathematical Library)Mathematical billiards describe the motion of a mass point in a domain with elastic reflections off the boundary or, equivalently, the behavior of rays of light in a domain with ideally reflecting boundary. From the point of view of differential geometry, the billiard flow is the geodesic flow on a manifold with boundary.
The Geography of Tourism and Recreation: Environment, Place and Space
An interesting piece of work, a comprehensive treatise which would be an imminently useful introductory text and reference for undergraduate studies in the Geography-Tourism-Recreation domain, a dynamic study field that is here to stay - for a long time!
The book elaborates one of Roman Jakobson's many brilliant ideas, i.e. his insight that the two cognitive strategies of the metaphoric and the metonymic are the end-points on a continuum of conceptualization processes. This elaboration is achieved on the background of Lakoff and Johnson's two-domain approach, i.e. the mapping of a source onto a target domain of conceptualization. Further approaches dwell on different stretches of this metaphor-metonymy continuum.
Superdiffusions and Positive Solutions of Nonlinear Partial Differential Equations
This book is devoted to the applications of probability theory to the theory of nonlinear partial differential equations. More precisely, it is shown that all positive solutions for a class of nonlinear elliptic equations in a domain are described in terms of their traces on the boundary of the domain.
Situated on Australia's eastern coastline is the continent's largest city, and only one travel reference shows you all its attractions and charms--DK's Eyewitness Travel Guide: Sydney. The guide's six district chapters--The Rocks and Circular Quay, City Center, Darling Harbour, Botanic Gardens and The Domain, Kings Cross and Darlinghurst, and Paddington--help you navigate through each area with accurate street-by-street maps and illustrated 3-D overviews.
