Thermodynamic Green functions in theory of superconductivity
A general theory of superconductivity is formulated within the thermodynamic Green function method for various types of pairing mediated by phonons, spin fluctuations, and strong Coulomb correlations in the Hubbard and t-J models. A rigorous Dyson equation for matrix Green functions is derived in terms of a self-energy as a many-particle Green function. By applying the noncrossing approximation...
متن کاملGreen Functions for Classical Euclidean Maxwell Theory
Recent work on the quantization of Maxwell theory has used a non-covariant class of gauge-averaging functionals which include explicitly the effects of the extrinsic-curvature tensor of the boundary, or covariant gauges which, unlike the Lorentz case, are invariant under conformal rescalings of the background 4-metric. This paper studies in detail the admissibility of such gauges at the classic...
متن کاملA Contribution to the Theory of Formal Meromorphic Functions
In my paper [F3] I more or less explicitly conjectured that if A is a complete local integral domain with maximal ideal m and if I = (tί9 , tn) is an ideal in A with n < dim (A) — 2, then Spec (A/7) — m is G3 in Spec (A) — m. This will be proved in this paper. Unfortunately the algebraisation-theorems for subsheaves in [F3] make great difficulties in this context, and I only can prove similar t...
متن کاملThe Green of Green Functions
lish Midlands, is famous for its association with Robin Hood, whose statue stands in the shadow of the castle wall. The Sheriff of Nottingham still has a special role in the city government although happily no longer strikes terror into the hearts of the good citizens. Recently a new attraction, a windmill, has appeared on the Nottingham skyline (see figure 1). The sails turn on windy days and ...
متن کاملOn the Green Functions of Gravitational Radiation Theory
Previous work in the literature has studied gravitational radiation in black-hole collisions at the speed of light. In particular, it had been proved that the perturbative field equations may all be reduced to equations in only two independent variables, by virtue of a conformal symmetry at each order in perturbation theory. The Green function for the perturbative field equations is here analyz...
