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.

An algebraic function Сѓ of a complex variable ? is a function which satisfies an equation of the form F(x, y) = 0, where F is a polynomial with complex coefficients; i.e., Сѓ is a root of an algebraic equation whose coefficients are rational functions of x….

In the last five years there has been very significant progress in the development of transcendence theory. A new approach to the arithmetic properties of values of modular forms and theta-functions was found.
