摘要

Analogues of the some basic notions of pluri-potential theory on strictly pseudo-convex domains in C~m are developed for Grauert tubes M_T in complexifications of real analytic Riemannian manifolds (M, g). In particular, the normalized logarithm of the complexified spectral projector ∏_(Iλ)~C (ζ,ζ-bar) is the analogue of the Siciak-Zaharjuta extremal pluri-subharmonic function. It is shown that 1/λ log ∏_(I/λ) (ζ,ζ-bar)→√p(ζ), where √p is the Grauert tube function. We give several applications to analytic continuations of eigenfunctions: to norm estimates, triple product integrals and to complex nodal sets.
