Two-loop QED radiative corrections to the decay pi0 to e+e-: the virtual corrections and soft-photon bremsstrahlung

-loop results with existing approximative calculations of QED corrections and findThis paper is devoted to the two-loop QED radiative corrections to the decay using any approximation and we take into account all th...

Pseudo-loop conditions

(or equation) of the form f(x1, horizontal ellipsis ,xn)approximate to f(y1, horizontal ellipsis ,yn) in an algebra is equivalent to the algebra forcing a loop into any graph with the identity. Such identities have since also been ...

Analytical model with flexible parameters for dynamic hysteresis loops modelling

Analytical model was proposed to find simple mathematical approximation of dynamic hysteresis loops of soft magnetic materials. It is based on pure phenomenological approach and consists in dynamic loop construction from fo...

Loop conditions for strongly connected digraphs

We prove that every strongly connected (not necessarily finite) digraph of algebraic length 1, which is compatible with an operation t satisfying a non-trivial identity of the form t(...) approximate to t(...), has a loop....

Interaction among Dislocation Loops in Deformed Metals

with wavy slip these dislocations are stored in the form of dislocation dipolar loops. The loops hinder the motion of fresh glide dislocations causing strain hardening . The loop distribution is governed by a balance law ....

Free loop spaces and cyclohedra.

In this note we introduce an action of module of cyclohedra on the free loop space. We will then discuss how this action can be used in an appropriate be used to recognize based loop spaces. We will also interpret one result of R.L....
