title: Algorithmic derivation of Dyson–Schwinger equations

description: Abstract We present an algorithm for the derivation of Dyson-Schwinger equations of general theories that is suitable for an implementation within a symbolic programming language. Moreover, we introduce the Mathematica package DoDSE^1which provides such an implementation. It derives the Dyson-Schwinger equations graphically once the interactions of the theory are specified. A few examples for the application of both the algorithm and the DoDSE package are provided.

title: Vectorizable wave propagation FORTRANcode for calculations of multiphoton dissociation

description: Abstract A vectorizable FORTRAN code for the ETA10 or other vector machines for numerical calculation of the time-dependent Schrödinger equation is presented. Preliminary results for the multiphoton dissociation of nitrogen oxide are shown. The applied electric field was approximated by a classical sinusoidal wave; both sinusoidal and cosinusoidal wave forms were tested, and the internuclear potential was taken to be a Morse function. Dissociation histories of three types were found. Title of program: ACTCON Catalogue Id: ACHK_v1_0 Nature of problem Time-dependent Schrodinger equation.

description: Abstract The new version of the Monte Carlo program for small-angle Bhabha scattering BHLUMI with an overall precision of 0.11% is presented. The main improvements are in the matrix element of the main multi-photon sub-generator based on the Yennie—Frautschi—Suura exponentiation, where the missing second-order terms in the leading-logarithmic (LL) approximation are supplemented and the contribution from the Z resonance is improved.
