A solution to Ward-Takahashi-identity in QED3
Yuichi Hoshino
Using spectral function of photon we find the reliable results for the effects of vacuum polarization for the dressed fermion propagator in three-dimensional QED.

A gauge covariant approximation to QED
Y. Hoshino
We examine the Dyson-Schwinger equation for the fermion propagator in quenched QED in three and four dimension based on spectral representation with vertex ansatz which preserves W…

The Gauge Technique in QED_{2+1}
Y. Hoshino
The Gauge Technique has been applied to QED in the quenched case with infrared subtraction. The behaviour of the fermion propagator near the threshold is then found to be \…
