We present a formal calculation of the infrared singularity structure of the fermion propagator in QED based on the Faddeev-Kulish asymptotic solution. The Renormalization program is reviewed in the context of the BPHZ subtraction scheme and a refinement of the Renormalization group methods is emplo

For two-dimensional anisotropic body with a parabolic boundary, the simple exphcit expressions of Green's functions are presented when a concentrated force f is applied at a point (x~, x Β°) in material for two kind boundary conditions, which are of free surJace and rigid surface, When parabolic curv
We determine a Green's function for the singular three-point third-order BVP and then we apply the classical Krasnosel'skiΘ's fixed point theorem on an also new cone. The emphasis is mainly that although this BVP does not admit a positive Green's function, the solution obtained is still positive. I
