A construction of an effective nonrenormalizable superpotential has been discussed within the approach of a four-dimensional heterotic superstring with free fermions on the world sheet. On the basis of N=2 superconformal theory, useful selection rule

We discuss applications of the quantile concept of trajectories and velocities to the propagation of electromagnetic signals in wave guides of varying cross section. Quantile motion is a general description of the transport properties of measurable c

Inverse spectral theory provides a theorem on the shifting of a single level, leaving all others unchanged, in a quantum-mechanical system over a finite range in one dimension. We show that the mechanism can be used to remove a pair of states from th

The quantum-mechanical motion of Gaussian wave packets on elliptical and hyperbolic orbits is calculated and shown in plots. The approximation scheme makes explicit use of energy and angular-momentum conservation thus guaranteeing controlled accuracy

The quantum properties of topological Yang-Mills theory are investigated in the light of the N = 2 supersymmetry observed in flat space. We construct a unique system of covariantly (partially) conserved currents which develop anomalies while preservi

We present the Monte Carlo even generator KRONOS for deep inelastic lepton-hadron scattering at HERA. KRONOS focusses on the description of electromagnetic corrections beyond the existing fixed order calculations.

We describe how to apply the unitary approximation to high energy scattering processes which involve the radiation of arbitrarily many photons. We compare our results to calculations of inclusive quantities using leading log resummation techniques we

The structure of the conserved or partially conserved currents of the topological Yang-Mills theory is discussed. These currents are then used to show that at the one-loop level the β-function reproduces the N =2 supersymmetry value. The result hold
