The book lays algebraic foundations for real geometry through a systematic investigation
of partially ordered rings of semi-algebraic functions. Real spectra serve as primary
geometric objects, the maps between them are determined by rings of functions associated
with the spectra. The many different possible choices for these rings of functions
are studied via reflections of partially ordered rings. Readers should feel comfortable
using basic algebraic and categorical concepts. As motivational background some familiarity
with real geometry will be helpful. The book aims at researchers and graduate students
with an interest in real algebra and geometry, ordered algebraic structures, topology
and rings of continuous functions
