Projective geometry is the geometry of vision, and this book
introduces students to this beautiful subject from an analytic
perspective, emphasising its close relationship with linear algebra
and the central role of symmetry. Starting with elementary and
familiar geometry over real numbers, readers will soon build upon
that knowledge via geometric pathways and journey on to deep and
interesting corners of the subject. Through a projective approach
to geometry, readers will discover connections between seemingly
distant (and ancient) results in Euclidean geometry. By mixing
recent results from the past 100 years with the history of the
field, this text is one of the most comprehensive surveys of the
subject and an invaluable reference for undergraduate and beginning
graduate students learning classic geometry, as well as young
researchers in computer graphics. Students will also appreciate the
worked examples and diagrams throughout.
Potatoes are one of the world's key food crops. Their nutritional
value, and the fact that they can be grown with relatively few
inputs in a wide range of environments, makes them an important
food security crop. However, yields in developing countries are
held back by factors such as poor cultivation practices and the
impact of pests and diseases, whilst more intensive systems need to
become more 'climate smart' both to minimise their environmental
impact and adapt to climate change. This volume reviews general
developments in breeding as well as improving particular traits
before discussing the challenges facing potato cultivation in
particular regions. Part 1 assesses recent research on plant
physiology and genetic diversity and their implications for
conventional, hybrid and marker-assisted breeding. Part 2 looks at
ways of breeding varieties with desirable traits such as stress
resistance or improved nutritional quality. The final part of the
book looks at ways of supporting smallholders in regions such as
Africa and Latin America. Although a separate species, the book
also includes selective coverage of research on sweet potato. With
its distinguished editor and international team of expert authors,
this will be a standard reference for potato scientists, growers,
government and non-government agencies supporting potato
cultivation. This volume is accompanied by a companion volume
looking at production and storage, diseases and sustainability.
