Global analytic geometry is a developing subject that gives an alternative/complementary approach to scheme theory in arithmetic geometry and analytic number theory. The starting point of this theory is in Vladimir Berkovich’s book about spectral theory and non-archimedean analytic geometry. It was then developped further by Jérôme Poineau.
Many interesting results on polynomial equations can be proved using the mysterious interactions between algebraic, complex analytic and p-adic analytic geometry. The aim of global analytic geometry is to construct a category of spaces which contains these three geometries. (Paugam08)
Global analytic geometry
combines non-archimedean and archimedean analytic geometry;
contains algebraic geometry as a sub-theory;
treats all places on equal footing, contrary to scheme theory. This implies that it is closer in spirit to the automorphic philosophy and Langlands program, and more historically to Tate’s proof of the functional equation.
The main aim of the theory is to define, using global analytic tools, a good category of analytic motivic coefficients, that would help in proving naturally:
Argument in favor of its use are:
the fact that archimedean factors are deeply related to (analytic) Hodge theory;
the fact that all proofs of parts of local Langlands program use deeply non-archimedean analytic spaces that are out of the scope of classical algebraic scheme theory.
