Construction of Hadamard states by characteristic Cauchy problem
We construct Hadamard states for Klein-Gordon fields in a spacetime M 0 equal to the interior of the future lightcone C from a base point p in a globally hyperbolic spacetime (M, g).Under some regularity conditions at future infinity of C, we identify a boundary symplectic space of functions on …
